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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Color display apparatus","description":"A color display apparatus includes a driving substrate, a color filter and a display layer.
