Array substrate, manufacturing method thereof and display device

Abstract

The invention discloses an array substrate, a manufacturing method of the array substrate and a display device, and relates to the technical field of display. The array substrate comprises a plurality of pixel units arranged in an array shape, each pixel unit comprises a first transparent electrode and a color light filtering unit which are arranged oppositely, the edges of the adjacent color light filtering units are overlapped, and an overlapping area is formed. First insulation layers are arranged between the first transparent electrodes and the color light filtering units, protrusions are arranged between the adjacent first transparent electrodes, the protrusions at least comprise parts, corresponding to the overlapping area, in the first insulation layers, and peaks of the protrusions are higher than the upper surfaces of the first transparent electrodes. When the array substrate is applied to the display device, the interference of electric fields between the adjacent first transparent electrodes can be reduced, color mixing and light leakage between the adjacent pixel units are reduced, and the display effect of the display device is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a preparation method thereof, and a display device. Background technique [0002] With the development and progress of thin film transistor liquid crystal display (TFT-LCD Display) technology, liquid crystal display devices have replaced cathode ray tube display devices and become mainstream display devices in the daily display field. [0003] At present, in order to continuously improve the quality of images displayed by liquid crystal display devices, the resolution thereof is continuously improved, in an effort to provide consumers with clearer and more realistic display images. The resolution is defined as the number of pixel units per inch in the liquid crystal display device. In this way, the higher the resolution, the more the number of pixel units per inch, resulting in each liquid crystal display device. The size of the pixel unit is getting...

Problems solved by technology

The resolution is defined as the number of pixel units per inch in the liquid crystal display device. In this way, the higher the resolution, the more the number of pixel units per inch, resulting in each liquid crystal display device. The size of the pixel unit is getting smaller and smaller, and the distance between the pixel electrodes in two adjacent pixel units is also getting smaller and smaller, such as figure 1 As shown, when a certain working voltage is applied to the pixel electrode 10, the electric field between two adjacent pixel electrodes 10 will be disturbed (as shown by the arrow in the figure), thereby affecting the quality of the displayed picture.

[0004] For example, if figure 2 As shown, when only the liquid crystal molecules 12 corresponding to a certain pixel unit (marked as a) are required to be deflected and the liquid crystal molecules 12 corresponding to another pixel unit (marked as b) adjacent to the pixel unit are not deflected, since the pixel unit The distance between a and pixel unit b is very small, so that the electric field between two adjacent pixel electrodes 10 interferes, resulting in liquid crystal molecules 12 between adjacent pixel unit a and pixel unit b, and pixel unit b The corresponding liquid crystal molecules 12 near the edge of the pixel unit a are deflected, so that the adjacent pixel units in the liquid crystal display device produce color mixing, light leakage and other phenomena, which affect the display effect of the liquid crystal display device
