Title:
PIXEL ELECTRODE AND LIQUID CRYSTAL DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2019/024322
Kind Code:
A1
Abstract:
A pixel electrode (1) and a liquid crystal display panel; the pixel electrode (1) is provided with a first sealing frame (15) which connects a trunk (11) and ends of all pixel electrode branches (13), and at least one second sealing frame (17) sleeved on the periphery of the first sealing frame (15) and connected to the trunk (11); by means of the first sealing frame (15) and the second sealing frame (17), an electric field at the edge of the pixel electrode (1) is regularized, thus orientation of liquid crystal molecules located at the edge of a sub-pixel is relatively uniform, which may eliminate dark lines at the edges all around the sub-pixels and improve optical transmittance of the liquid crystal display panel; in addition, a new domain is formed between the first sealing frame (15) and the second sealing frame (17), which may further improve the viewing angle of the liquid crystal display panel at low and medium gray levels.
