Title:
DISPLAY SUBSTRATE AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/057021
Kind Code:
A1
Abstract:
Disclosed are a display substrate and a liquid crystal display device. The display substrate comprises: a base substrate, the base substrate comprising a gate layer, a source and drain layer, an active layer, and a planarization layer; a pixel electrode at least partially covering the planarization layer, and connected to the source and drain layer by means of a via; and a reflective layer at least partially covering the pixel electrode, wherein the reflective layer is not provided on the pixel electrode at the via. In the present utility model, the reflective layer at the via is removed to reduce the area of the reflective layer, thereby reducing the reflectance of the layer in a black-screen state, and improving the contrast ratio. The present utility model is applicable to half-reflection half-transmission or total-reflection liquid crystal display panels, and provides a planarization layer to improve the overall smoothness.
