The method includes forming a first pixel electrode layer on a color resist layer, forming a planarization layer on the first pixel electrode layer, and forming a second pixel electrode layer that is in engagement with the first pixel electrode layer on the planarization layer so as to achieve planarization of the pixel electrode layer to the maximum extent. Further, the second pixel electrode layer includes a pixel electrode block that is located in each sub pixel zone and has a lateral border located above a scan line and a longitudinal border located above a signal line so as to achieve self-shielding of light for the scan line and the signal line, allowing for omission of lateral and longitudinal black matrixes. Further, a dot-like black matrix is formed on a glass substrate at a location corresponding to a TFT on the array substrate to shield light for a site of a channel thereby simplifying the manufacturing process and increase the aperture ratio."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for manufacturing COA liquid crystal panel comprising color resist blocks having first and second intersection zones and COA liquid crystal panel","description":"The present invention provides a method for manufacturing a COA liquid crystal panel and a COA liquid crystal panel.
