Embodiment Construction

[0029] like figure 2 As shown, the liquid crystal display panel 2 of the preferred embodiment of the present invention has a color filter substrate 21, an array substrate 23, and a liquid crystal layer 27 interposed therebetween. The color filter substrate 21 has a layered structure, and under the arrangement of the bumps 20 is a transparent conductive layer 21a, a color filter 21b, and a transparent substrate 21c in sequence. The array substrate 23 has a layered structure, including a transparent conductive layer 23a having slits 25 corresponding to the bumps 20 , a protective layer 23b , a dielectric layer 23c , and a transparent substrate 23d . In the dark state, the liquid crystal molecules 27a near the alignment bump 20 are different from the liquid crystal molecules 27b in other regions, and are not vertical to the substrate. The transparent conductive layers 21a and 23a can be the same or different materials, such as indium tin oxide (ITO), aluminum zinc oxide (AZO), ...

Abstract

The invention provides a liquid crystal panel with an arrangement bump of an appropriate optical density (OD). The liquid crystal panel comprises a substrate of at least one arrangement bump, an opposite substrate and a liquid crystal layer, wherein the opposite substrate is arranged opposite to the substrate; and the liquid crystal layer is positioned between the substrate and the opposite substrate. The OD is larger when the thickness of the arrangement bump is larger. When the unit of the OD is mum, the OD of the arrangement bump at every mum thickness is 0.3-3, and is preferably 0.8-1.3. By adopting the liquid crystal panel, the problem of dark state light leakage caused by the arrangement bump can be solved.

Description

[0001] This application is a divisional application of the application dated November 20, 2006, the application number is 200610160424.X, and the invention name is "liquid crystal panel". technical field [0002] The invention relates to a liquid crystal panel, in particular to the design of arranging bumps in the liquid crystal panel. Background technique [0003] Most of the current mainstream wide viewing angle liquid crystal panels adopt Multi-domain Vertical Alignment (MVA) technology, the principle of which is to form alignment protrusions on the substrate so that the liquid crystal molecules are perpendicular to the alignment protrusions. By designing the pattern of arranging the bumps, the liquid crystal molecules can form a double-region arrangement, a four-region arrangement, or even a multi-region arrangement. Since the direction of the liquid crystal molecules is not only facing a single direction in the bright state, the user can view normal images at different ...
