The color display layer disposed on the first surface of the transparent active element array substrate.
Claims13
A display device comprising:
- a transparent active element array substrate having a transparent base and a transparent thin film transistor, a first surface and a second surface, wherein the transparent thin film transistor is disposed on the transparent base and under the first surface, and the second surface is opposite to the first surface;
- a color display layer disposed on the transparent thin film transistor and capable of displaying color images on two opposite sides thereof paralleled with the first surface of the transparent active element array substrate, wherein the color display layer comprises:
- a first color filter layer;
- and
- a display layer disposed between the transparent thin film transistor and the first color filter layer, wherein the display layer is an electrophoretic layer to reflect lights to the two opposite sides of the color display layer;
- and
- a second color filter layer disposed between the display layer and the transparent thin film transistor, whereby the display device is capable of displaying color images on both sides thereof paralleled with the first surface of the transparent active element array substrate.
