In this embodiment, the display device does not need to provide the light source module 30, and the reflective layer 26 reflects the external ambient light to realize the image display. That is, the display device in this embodiment can be used as an electronic book. When the ambient light is strong, the reflective layer 26 reflects the ambient light to realize the picture display. And the fluorescent layer 261 can absorb part of light energy and store the light energy, and when the light is darker, the fluorescent layer 261 can emit light and compensate the brightness. For example, in a color display, the color resist layer absorbs a portion of light, so that the display device displays a dark picture, and the fluorescent layer 261 can emit light and compensate the brightness. Of course, the color display state and the black-and-white display state of the display device can be switched according to the intensity of the external ambient light. For example, when the external ambient light is strong, the display device uses a color display state; when the external ambient light is weak, the display device uses a black-and-white display state.
Further, as shown in fig. 4, the fluorescent layer 261 may be distributed on the reflective layer 26 in a dot shape; as shown in fig. 5, the fluorescent layer 261 may also be distributed on the reflective layer 26 in a stripe shape, so as to avoid the reflective capability of the reflective layer 26 from being greatly reduced due to the fluorescent layer 261 completely covering the reflective layer 26.
