Problems solved by technology

In order to solve this problem, the methods currently used mainly include: extrapolating the edge of the swastika pattern to the black matrix, using the black matrix to cover the edge of the swastika pattern, or designing the specific position of the edge of the upper electrode as a radioactive narrow slit, the force of the ITO electrode fringe electric field on the liquid crystal molecules is moved outward, so that the horizontal and vertical dark lines caused by the fringe field effect are moved out of the ITO opening area, but these methods only weaken the horizontal and vertical dark lines on the edge of the swastika dark lines , but has no effect on the cross pattern in the middle of the swastika pattern

Embodiment Construction

[0027] In order to explain the embodiments of the present invention or the technical solutions in the prior art more clearly, the following briefly introduces the drawings that need to be used in the embodiments. The drawings in the following description are only part of the embodiments of the present invention. For those of ordinary skill in the art, without creative work, other drawings can be obtained from these drawings.

[0028] The existing liquid crystal display panel includes a plurality of sub-pixel units. Each sub-pixel unit includes an upper electrode, an upper alignment film, a liquid crystal layer, a lower alignment film, and a lower electrode. The sub-pixel unit includes four light-transmitting regions, and adjacent light-transmitting regions The regions have different alignment directions, and the principle that adjacent light-transmitting regions have different alignment directions is as follows:

[0029] The upper alignment film and the lower alignment film are ver...

Abstract

The invention provides a liquid crystal display panel and a display device applying the liquid crystal display panel.The liquid crystal display panel comprises a plurality of sub-pixel units.Each sub-pixel unit comprises an upper electrode, a liquid crystal layer and a lower electrode, wherein the sub-pixel unit comprises four photic zones, the adjacent photic zones have different alignment directions, and the junction of the adjacent photic zones comprises a horizontal junction or a vertical junction.The liquid crystal display panel further comprises slots formed in the corresponding positions of the upper electrode and / or the lower electrode corresponding to the junction of the adjacent photic zones, and the opening direction of the slots is parallel to the alignment direction of liquid crystal molecules in the photic zones where the slots are formed.Due to the fact that the slots are formed in the upper electrode or the lower electrode, and the effect of weakening corresponding dark fringes is achieved, the light transmittance of the whole liquid crystal display panel is improved, and the display device applying the liquid crystal display panel has the higher light transmittance.

Description

Technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel and a display device using the liquid crystal display panel. Background technique [0002] UV2A (UltravioletVerticalAlignment) technology is a technology that uses ultraviolet rays to align the liquid crystals in a vertical alignment liquid crystal display. The basic principle is to coat an alignment film of a polymer material that reacts to ultraviolet rays on a glass substrate. , The polymer main chain on the surface of the alignment film will tilt along the direction of ultraviolet radiation, so that the liquid crystal molecules can be tilted along this main chain direction. At present, this technology is mainly applied to vertical alignment mode liquid crystal displays with large viewing angles, which improves the aperture ratio, contrast, and response speed of large viewing angle liquid crystal displays. [0003] However, becau...
