A color display apparatus includes a driving substrate, a color filter and a display layer. The driving substrate has a display region and a non-display region, and at least a first alignment mark is disposed on the non-display region. The color filter is opposite to the driving substrate. The color filter includes a substrate and a filter layer disposed on the substrate. The substrate has a first region corresponding to the display region and a second region corresponding to the non-display region. The filter layer includes color filter patterns located on the first region and at least a second alignment mark located on the second region and corresponding to the first alignment mark. The display layer is disposed between the driving substrate and the color filter. Alignment precision between the driving substrate and the color filter of the color display apparatus is improved. Besides, a color filter is also provided. The color display apparatus and the color filter provided in the utility model can be used to provide the display quality.
Description
technical field [0001] The invention relates to a display device, in particular to a color display device and a color filter thereof. Background technique [0002] With the progress and development of display technology, various display devices have come out one after another, and are widely used in daily life. In order to meet the requirement of colorization, some display devices use color filters to display color images. [0003] figure 1 is a schematic diagram of an existing color display device, and figure 2 yes figure 1 Schematic diagram of the top view of the color filter. Please refer to figure 1 and figure 2 , the existing color display device 100 includes a driving substrate 110 , a color filter 120 and a display layer 130 . The color filter 120 is opposite to the driving substrate 110 , and the display layer 130 is disposed between the driving substrate 110 and the color filter 120 . The driving substrate 110 has alignment marks 111 . The color filter 12...
