Field of the Invention The present invention relates to an image display system including a liquid crystal display panel, and more particularly to an electrode structure of a vertical alignment type liquid crystal display panel. [Prior Art] A vertical alignment (VA) liquid crystal display is a liquid crystal display capable of achieving high contrast and wide viewing angle, and is conventionally designed to make a vertical alignment type liquid crystal display (VA-LCD) stable and symmetrical. The multi-domain usually divides a sub-pixel of the VA-LCD into 2 to 3 smaller sub-pixel regions, so that there are 2 to 3 multi-quadrant regions in a sub-quartz. This is achieved by using a patterned transparent electrode layer on the array substrate, such as indium tin oxide (ITO), or a transparent electrode layer on a color filter substrate, such as a pattern of indium tin oxide. Please refer to FIG. 1 , which is a schematic diagram showing a transparent electrode layer on an array substrate in a sub-decene of a conventional vertical alignment type liquid crystal display, and the transparent electrode layer 1 on the array substrate in a sub-quartz has 2 slits ll. Next, please refer to FIG. 1 , which is a schematic diagram showing a planar view of a transparent electrode layer on a color filter substrate in a sub-decant of a conventional vertical alignment type liquid crystal display. The transparent electrode 20 has three openings 21. Please refer to FIG. 1C, which is a schematic diagram showing the plane of the transparent electrode layer 10 on the array substrate and the transparent filter 20 on the substrate of the color filter 0773-A34028TWF P2008051 4 201027203 in a sub-single of the conventional vertical alignment type liquid crystal display. The secondary halogen 16 is defined by two adjacent scan lines 12 and two adjacent data lines 14, the slit 11 of the transparent electrode layer 10 on the array substrate and the transparent electrode layer 20 on the color filter substrate. The openings 21 are matched to each other such that one secondary pixel 16 is divided into three multi-quadrant regions, and the contact holes 30 are disposed in one opening of the transparent electrode layer 20 on the color filter substrate. The responsiveness of the vertical alignment type liquid crystal display can be improved by increasing the slit width of the transparent electrode layer 10 on the array substrate and/or increasing the opening size of the transparent electrode 20 on the color filter substrate, but the transparent electrode layer on the array substrate The larger the opening of the transparent electrode layer on the slit and the color filter substrate, the more obvious the display sensation caused by the touch panel when it is applied to the touch panel. In addition, the larger the opening of the transparent electrode layer on the array substrate and the opening of the transparent electrode layer on the color filter substrate, the lower the transmittance of the display and the higher the driving voltage of the display. In view of this, there is a need in the industry for a vertical alignment type liquid crystal display that can meet the requirements of improving the response speed, reducing the display unevenness of the touch panel, increasing the transmittance, and lowering the driving voltage. SUMMARY OF THE INVENTION The present invention provides an image display system including a liquid crystal display panel, the liquid crystal display panel including: a first substrate having a plurality of mutually perpendicular tributary lines and scan lines 'two adjacent data lines And defining a primary pixel between the two adjacent scanning lines; the first transparent electrode layer is disposed on the first substrate and located in the secondary halogen; the second substrate is disposed opposite to the first substrate and has an inner surface; The second transparent electrode layer is disposed on the inner surface of the second substrate 0773-A34028TWF P2008051 5 201027203, and corresponds to the secondary halogen, wherein the second transparent electrode layer located in the secondary halogen has only one pattern; and the liquid crystal layer is disposed on Between the first substrate and the second substrate, wherein a plurality of liquid crystal molecules in the liquid crystal layer are aligned perpendicular to the first substrate and the second substrate. In order to make the above-mentioned objects, features, and advantages of the present invention more comprehensible, the following description will be described in detail with reference to the accompanying drawings: [Embodiment] The present invention is directed to a vertical alignment type liquid crystal display panel (VA-LCD).
