Embodiment Construction

[0079] Please refer to FIG. 3 , which is a graph showing the relationship between the applied voltage and the light transmittance of the multi-area vertical alignment liquid crystal display device of the present invention. As shown in Figure 3, Curve A and Curve B respectively represent the V-T curves (curves) measured by two different liquid crystal cell gaps, and Curve C is the V-T curve (curve) obtained by mixing Curve A and Curve B ( curve). The present invention is to form different liquid crystal cell gaps in the panel to compensate each other through the different liquid crystal cell gaps to reduce the difference between the V-T curve (curve) when looking straight ahead and squinting, thereby improving problems such as light leakage or color shift.

Abstract

This invention relates to one multi-area vertical layout LCD panel and film transistor tube array baseboard and its process method, wherein, the array baseboard comprises baseboard, multiple data layout lines, scanning line and pixel structure; the data layout line and scan line are set on the baseboard to define multiple pixel areas separately set into each pixel area composed of film transistor tube, pixel electrode and medium underlay; the film transistor tube is connected to the data layout line and scan line and the pixel electrode is located above the transistor tube with multiple main silts; the medium layer is on the baseboard and between the pixel electrode and baseboard to generate several inclination directions.

Description

technical field [0001] The invention relates to a display panel, an active element array substrate and a manufacturing method thereof, and in particular to a multi-region vertical alignment type liquid crystal display panel, a thin film transistor array substrate and a manufacturing method thereof. Background technique [0002] Existing liquid crystal displays tend to develop towards high brightness, high contrast, large area display and wide viewing angle. In order to improve the viewing angle of the liquid crystal display, various wide viewing angle technologies have been proposed. Currently, the more common wide viewing angle liquid crystal displays such as multi-domain vertical alignment (Multi-Domain Vertical Alignment, MVA) liquid crystal display, in-plane switching (In-Plane Switching, IPS) liquid crystal display and fringe field switching (Fringe Field Switching, FFS) liquid crystal display and so on. As far as the multi-area vertical alignment liquid crystal displa...
