Embodiment Construction

[0031] For a horizontal electric field type liquid crystal display device using a collimated light source (hereinafter referred to as a collimated light source liquid crystal display device), its pixel electrodes and common electrodes are both arranged on the array substrate, and the pixel electrodes and / or common electrodes are slit electrodes for A horizontal driving electric field is formed to drive liquid crystal molecules to deflect and control the display process. Wherein, the slit electrode is composed of multiple sub-electrodes, and there are slits between adjacent sub-electrodes. The slits of the existing slit electrodes are designed to be equal in width. Although the light emitting angle can be ensured, color crossing defects are prone to occur. This is the technical problem to be solved by the present invention.

[0032] Before describing the technical solution of the present invention, first briefly introduce the main structure and working principle of the liquid c...

Abstract

The present invention provides a display substrate, a display panel, and a display device. The display substrate includes a plurality of sub-pixel regions, and each sub-pixel region includes a light-shielding region and opening regions on both sides; each sub-pixel region is provided with a first transparent electrode The first transparent electrode includes a first electrode unit located in the light-shielding area, the first electrode unit includes a plurality of first sub-electrodes, and there are first slits between adjacent first sub-electrodes; from the center of the light-shielding area to the light-shielding area In the direction of the sides where the area and the opening area meet, the width of the first slit shows an increasing trend, and the liquid crystal corresponding to the smaller slit in the central area of ​​the light-shielding area can form a larger curvature of the liquid crystal prism, which is more sensitive to light. The deflection angle is large, the light output angle is large, and the light output efficiency is guaranteed. The liquid crystal corresponding to the wide slit in the edge area can form a small liquid crystal prism curvature, and the deflection angle of the light is small, and the light output angle is small, ensuring that the light will not It emits to the adjacent sub-pixel area to solve the cross-color problem.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate, a display panel and a display device. Background technique [0002] For a transverse electric field liquid crystal display device, the light emitted by the backlight needs to pass through two layers of polarizers, which has low transmittance and high power consumption. In order to solve the above-mentioned technical problems, the collimated light source display technology is adopted in the prior art. The collimated light source display technology projects the collimated light to the liquid crystal layer through the light-taking port, and the position of the light-taking port is correspondingly provided with a light-shielding pattern. When the driving electric field is not applied, the collimated light at the light-taking port is blocked by the light-shielding pattern to realize the dark state display. When the driving electric field is applied, the ...
