The anti-reflection light-shielding layer blocks light from the display device (such as from the backlight module) from passing through the color filter. The light-colored red, green, and blue primary color matrix regions (r/G/B) can be controlled by the drive 1C to filter the light passing through the display device to become the color desired by us. Presenting an overall image. The color matrix is formed by a color resist, which may be in a transparent substrate 102 by a pigment disperse, a reverse printing, or an ink jet.

Referring now to the second drawing, which is a cross-sectional view of a liquid crystal panel 15 having a color filter 1A according to an embodiment of the present invention, the composition of each layer of the liquid crystal panel 150 is depicted. In the present invention, the color filter 100 is an upper substrate as a whole of the liquid crystal panel 150, and defines a space 159 for accommodating the liquid crystal molecules 158 together with a lower transparent substrate 156 as a lower substrate. The color filter 1A and the lower transparent substrate 156 are separated by a seal frame 160 and seal the space 159 into which the liquid crystal molecules 158 are injected. A transparent conductive layer is formed on the lower transparent substrate 156 as the lower transparent electrode (ie, the pixel electrode Pixel electrode) 162 of the liquid crystal panel 150, and the corresponding transparent electrode 124 on the color filter 100 serves as the upper electrode of the liquid crystal panel I50.

The operation of the display device having the color filter of the present invention will be described below. In this embodiment, the liquid crystal panel 15 is provided with a backlight (bl) as a source of image light of the display device. The backlight BL first passes through the polarizer 154 to remove the natural light without polarity. The light is converted into a polarized light (PL, p〇iarize (j light), so that the transmitted light can be controlled by an applied electric field to obtain a visually bright and dark change. The polarized light PL then passes through the lower transparent substrate 156 into the liquid crystal molecule 158 space 159. Depending on the twist angle of the liquid crystal molecules 158, the passing polarized light PL exhibits different gray scale expressions and comes to the color polarizer 1 〇〇 portion of the display device.

The color filter of the transparent thin film solar cell of the present invention has the advantages that the color filter can filter the light and present the image, and can also receive the incident from the outside. Light (such as sunlight, illumination, etc.) is photoelectrically converted to generate additional electrical energy for use with a display device (such as a liquid crystal panel 15). Thus, during use of the display device (typically in a lighted environment) It may affect the image performance of the display device itself, and at the same time generate power for the display device to save energy consumption of the display device. In the case where the display device is not activated, the color filter of the present invention may also Continuously receiving external light energy to pre-store it in a power storage unit for later display of the device.
