Abstract

The present invention provides a COA substrate and a display panel, the COA substrate includes a substrate, a thin film transistor and a color resistance layer, the thin film transistor is arranged on the substrate, the color resistance layer is arranged on the thin film transistor, The color resistance layer includes a plurality of overlapping color resistances, wherein the thin film transistor has a first groove formed in the overlapping area corresponding to the color resistance layer, and the color resistance layer fills the first groove Inside; by forming the first groove in the overlapping area of ​​the color resistance layer corresponding to the thin film transistor, so that when the color resistance layer is formed, the overlapping part of the color resistance layer will be filled into the first groove, thereby reducing the color resistance layer The overlapping part of the COA substrate will not bulge upwards, so that the side of the color-resist layer close to the liquid crystal layer is flat, thereby alleviating the technical problem that the color-resist layer of the existing COA substrate has protrusions, which leads to abnormal liquid crystal orientation and thus affects the display. .

Description

technical field [0001] The invention relates to the field of display technology, in particular to a COA substrate and a display panel. Background technique [0002] In order to increase the aperture ratio of existing display panels, the color-resist layer is arranged on the side of the array substrate to obtain a COA substrate (Color Filter On Array, where the color filter is arranged on the array substrate), so that there is no need to set a black color on the color-resist layer. The matrix improves the opening ratio, but in the process of forming the color resistance, in order to facilitate the formation of the color resistance, a certain overlapping part will be formed at the junction of adjacent color resistances, so that the color resistance layer will form a certain protrusion at the junction, while The protrusion of the color-resist layer will cause abnormal alignment of the liquid crystal, thereby affecting the display and resulting in poor display.
