Description

Multi-region vertical alignment type liquid crystal display

The present invention relates to a wide viewing angle liquid crystal display, and more particularly to a Multi-Domain Vertical Alignment (MVA) liquid crystal display. Background technique

Current liquid crystal displays are moving toward increasing display, high brightness, high contrast, large viewing angle, large area, and full color. However, liquid crystal displays still have problems such as narrow viewing angle range and high price. Therefore, how to increase the range of viewing angles is one of the urgent problems to be improved. Many wide viewing angle liquid crystal display solutions have been proposed, including multi-region vertical alignment liquid crystal displays, In-Plane Switching (IPS) liquid crystal displays, and Fringe Field Switching (FFS) liquid crystals. Display and more. Wherein, the multi-region vertical alignment type liquid crystal display utilizes the liquid crystal region for display to be divided into a plurality of regions, so that the liquid crystal molecules are tilted in a plurality of directions, thereby increasing the viewing angle range of the liquid crystal display.

1 is a schematic plan view showing one of pixels (pixels) of a known multi-region vertical alignment type liquid crystal display. Referring to Fig. 1, a scan wiring 102, a data wiring 104, a thin film transistor 120, and a pixel electrode 112 are disposed on a substrate (not shown). The thin film transistor 120 includes a gate 106, a channel layer 108, and a source/drain 110a/110b. The gate 106 is electrically connected to the scan line 102, and the source 110a is electrically connected to the data line 104. The pole 110b is electrically connected to the pixel electrode 112 through the contact window 116.

A plurality of strips (Protrusion) 118. Or a plurality of strip-like protrusions 118 are disposed on the pixel electrode 112, and are more in an electrode film (not shown) on another substrate having a color filter layer. Strip slits 114. Thus, by the combination of the slits 114 and the protrusions 118, the liquid crystal molecules disposed between the two substrates can be tilted in multiple directions, thereby achieving the purpose of increasing the viewing angle range of the liquid crystal display.

Although the multi-region vertical alignment type liquid crystal display can increase the viewing angle range by the design of the protrusions 118 and the slits 114, it has a good left and right viewing angle.

Accordingly, the above-described multi-region vertical alignment type liquid crystal display is one of the types of wide viewing angle liquid crystal displays, but its subsequent development may be limited by the above problems. Accordingly, there is still a need to develop a multi-region vertical alignment type liquid crystal display having more liquid crystal tilting directions. Summary of the invention
