Abstract

A color display device including a lower substrate, a driving array, a display layer, a color filter substrate and a transparent substrate is provided. The driving array is disposed on the lower substrate. The display layer is disposed on the driving array and includes a first region and a second region. The color filter substrate is disposed on the display layer and is located in the first region. The transparent substrate is disposed on the display layer and is located in the second region. The color display device has a high light reflectivity, thereby improving the display quality of the color display device.

Claims

1. A color display device, comprising:

a lower substrate;

a driving array disposed on the lower substrate, the driving array comprising a first region and a second region;

a first front plane laminate disposed on the driving array and located in the first region;

a second front plane laminate disposed on the driving array and located in the second region; and

a color filter substrate disposed on the first front plane laminate.

2. The color display device as claimed in claim 1, further comprising a transparent substrate disposed on the second front plane laminate.

3. The color display device as claimed in claim 2, wherein the color filter substrate comprises:

a transparent base plate; and

a color filter layer comprising a plurality of color photoresist patterns, the color filter layer being disposed between the transparent base plate and the first front plane laminate.

4. The color display device as claimed in claim 3, wherein the transparent base plate is either a transmissive glass or an optical plastic film.

5. The color display device as claimed in claim 3, wherein a thickness of the transparent substrate is equal to a thickness of the color filter layer and a thickness of the transparent base plate.

6. The color display device as claimed in claim 5, wherein the transparent base plate is integrated with the transparent substrate.

7. The color display device as claimed in claim 2, wherein the transparent substrate is either a transmissive glass or an optical plastic film.

8. The color display device as claimed in claim 1, wherein an area ratio of the first region and the second region is in a range from 20% to 80%.

9. The color display device as claimed in claim 1, wherein each of the first front plane laminate and the second front plane laminate includes an electrophoretic layer and a transparent electrode layer disposed on the electrophoretic layer.

10. The color display device as claimed in claim 9, wherein the electrophoretic layers of the first front plane laminate and the second front plane laminate black and whit electrophoretic layers.
