Title:
MULTI-DOMAIN LIQUID CRYSTAL DISPLAY
Document Type and Number:
WIPO Patent Application WO/2020/087582
Kind Code:
A1
Abstract:
Disclosed is a multi-domain liquid crystal display, comprising an LCD panel (1), an incident-side polarizer (2) and an emergent-side polarizer (3). The LCD panel (1) comprises multiple pixel structures (5) arranged in an array, wherein each pixel structure (5) comprises at least two sub-pixels (10) which respectively correspond to different colors, each sub-pixel (10) is divided into at least four domain areas (15), each domain area (15) comprises multiple branch electrodes (16) which are parallel to each other and distributed at intervals, and included angles (θ) between the branch electrodes (16) of the at least two sub-pixels (10) which respectively correspond to different colors and a transmission axis of the incident-side polarizer (2) are different. Compared with the prior art, on the basis of a multi-domain structure, the multi-domain display further enables the branch electrodes (16) of the sub-pixels (10) corresponding to different colors and transmission axes of the polarizers (2) and (3) to have different included angles (θ), so that the degree difference of the voltage transmission rate curve deviation of red, green and blue sub-pixels (10) under squinting and emmetropia is reduced, the visual angle color shift problem of the liquid crystal display panel (1) can be effectively improved, and the structure and a manufacturing method are simple and do not result in other additional manufacturing process and a cost impact.
