Embodiment Construction

[0061] In order to improve the color shift problem of the liquid crystal display panel at a large viewing angle, for example, greater than or equal to 60 degrees, it is necessary to make the liquid crystal molecules in the same pixel unit display different arrangements to show different display brightness. Therefore, a capacitive coupling method or a method of adding transistors has been developed in the known technology, so that a single pixel unit can display different display luminances at the same time. However, these methods will affect the display aperture ratio of the liquid crystal display panel, and at the same time increase the complexity of the driving method of the liquid crystal display panel.

[0062] To this end, the present invention proposes a pixel unit, which utilizes the configuration of the ultraviolet light absorption pattern and appropriate process technology to form multiple alignment regions, wherein the liquid crystal molecules in different alignment r...

Abstract

The invention provides a pixel unit, a LCD panel, an electro-optical device and a producing method thereof. Wherein the pixel unit has a display region. The pixel unit comprises a first substrate, a second substrate, a liquid crystal layer and at least one ultraviolet light absorption layer. The second substrate is arranged parallel to the first substrate, and the liquid crystal layer is disposed between the first substrate and the second substrate. The ultraviolet light absorption pattern is disposed between the first substrate and the second substrate. Part of the display region overlaps with the ultraviolet light absorption pattern to define at least one first direction region, and the part which does not overlap with the ultraviolet light absorption pattern defines at least one second direction region. The liquid crystal molecules in the liquid crystal layer are disposed with different tilt angles in the first direction region and in the second direction region. The invented LCD panel and pixel unit facilitate improving color cast condition of large visual angle. Display quality of the electro-optical device is enhanced when the invented LCD panel and pixel unit are used in the electro-optical device.

Description
