However, in order to ensure the display effect of the liquid crystal panel, the thickness of the color filter is about ten times the thickness of the drain of the thin film transistor, and the height difference between the two will make the inclination angle of the side wall of the opening approach 90 degrees. It is not conducive to the deposition of the transparent conductive layer on the opening, and the liquid crystal display panel may have the risk of electrostatic discharge (ElectroStatic Discharge, ESD)

The invention discloses a color filter array substrate and a manufacturing method thereof. The color filter array substrate includes a transparent substrate, a thin film transistor, a color filter unit and a pixel electrode. The color filter unit is located on the groove of the transparent substrate, and is used for converting the light entering the color filter unit into light of a predetermined color. The pixel electrode is located on the color filter unit and coupled to the drain of the thin film transistor, and is used for, when the gate of the thin film transistor receives a scan pulse, according to the level of the electrical signal sent to the drain, The rotation direction of the liquid crystals of the liquid crystal layer is controlled. In the present invention, the color filter unit is formed on the first groove and the pixel electrode is formed on the color filter unit, without forming an opening on the protective layer to connect the drain of the thin film transistor to the pixel electrode , so the present invention can omit the etching process for forming openings on the protection layer.
Description
technical field [0001] The invention relates to a liquid crystal display panel and a manufacturing method thereof, in particular to a color filter array substrate and a manufacturing method thereof. Background technique [0002] Displays with advanced functions have gradually become an important feature of today's consumer electronics products. Liquid crystal displays have gradually become widely used in various electronic devices such as mobile phones, personal digital assistants (PDAs), digital cameras, computer screens or laptop screens with high resolution. rate color screen monitor. [0003] A traditional liquid crystal display panel is composed of a color filter substrate (color filter), a thin film transistor array substrate (TFT array substrate), and a liquid crystal layer disposed between the two substrates. However, the resolution of this liquid crystal display panel is poor, the aperture ratio of the pixels is low, and misalignment is likely to occur when the col...
