LIQUID CRYSTAL DISPLAY SUBSTRATE, LIQUID CRYSTAL DISPLAY PANEL, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

A liquid crystal display substrate, a liquid crystal display panel, and a liquid crystal display device. The liquid crystal display substrate comprises a base substrate (1), a planarization layer (14) arranged on the base substrate (1), and a liquid crystal alignment layer (15) arranged on the planarization layer (14), where the planarization layer (14) of the liquid crystal display substrate is provided with a groove (16) in proximity to the edge.
