Problems solved by technology

Due to the deviation of the array substrate and the color filter substrate in the process of grouping, it is necessary to increase the width of the black matrix (BM) to avoid light leakage caused by the deviation of the group, but the increase in the width of the black matrix will make the light transmission of the display panel The area of ​​the area is reduced, thus affecting the aperture ratio of the display panel

Abstract

The present invention provides a display panel and a manufacturing method thereof. The display panel comprises a substrate, a plurality of thin film transistor elements, a plurality of color filter layers with different colors, and a plurality of auxiliary color filtering patterns. The thin film transistor elements and the color filter layers are disposed on the substrate and positioned in corresponding pixel areas, and each color filter layer is provided with an opening to expose the corresponding thin film transistor element. The auxiliary color filtering patterns are respectively disposed in the openings of the color filter layers and have the same light penetrating wave length frequency spectrum. The color filter layers of the display panel are disposed on the array substrate, and therefore the opening ratio can be effectively improved. In addition, the auxiliary color filtering patterns having the same color are covered over the thin film transistor elements in the pixel areas used for display different colors, so that leakage currents of all the thin film transistor elements are identical, and the thin film transistor elements have consistent element characteristics without color cast.

Description

technical field [0001] The present invention relates to a display panel and a manufacturing method thereof, in particular to a display panel with high aperture ratio and low color shift and a manufacturing method thereof. Background technique [0002] A display panel such as a liquid crystal display panel is usually composed of an array substrate (Array substrate) and a color filter substrate (Color Filter substrate, CF substrate). The array substrate is provided with thin film transistor elements and peripheral circuits, and the color filter substrate A color filter layer such as a red filter layer, a green filter layer and a blue filter layer is disposed on the substrate. Due to the deviation of the array substrate and the color filter substrate in the process of grouping, it is necessary to increase the width of the black matrix (BM) to avoid light leakage caused by the deviation of the group, but the increase in the width of the black matrix will make the light transmiss...
