Embodiment Construction

[0027] The inventor found through research that the reasons for the light leakage of the IPS mode liquid crystal display device in the prior art are:

[0028] Different from the traditional TN mode, the IPS mode liquid crystal display device applies driving voltage electrodes that are all arranged on the surface of the TFT array substrate, and the liquid crystal molecules rotate in a plane parallel to the TFT array substrate and the filter plate. In the traditional TN mode, generally only the distance from the top of the spacer to the edge of the shading pattern can be controlled. In order to improve the product quality of the color filter substrate and meet the high-definition requirements of the IPS mode liquid crystal display device, the size of the light shielding pattern on the color filter substrate is continuously reduced. reference figure 2 At this time, the distance between the spacer 25 and the edge of the light-shielding pattern is also reduced accordingly. However, i...

Abstract

The invention discloses a light filter plate for a liquid crystal display panel in an IPS (in-plane switching) mode and a liquid crystal display device. The light filter plate comprises a substrate, shading patterns, light filter layers, a flat layer and photo spacers. The shading patterns and the light filter layers are positioned on the substrate and have overlap regions; the flat layer covers the shading patterns and the light filter layers; the photo spacers are positioned on the flat layer and are positioned above the overlap regions of the light filter layers and the shading patterns, and the distances from the edges of the bottoms of the photo spacers to the edges of the shading patterns in the direction parallel to the surface of the substrate are larger than or equal to 3 micrometers and are smaller than or equal to 6 micrometers. According to the technical scheme, the light filter plate and the liquid crystal display device have the advantages that poor liquid crystal orientation of the light filter plate can be prevented; poor display of the liquid crystal display device can be prevented after an array substrate of the liquid crystal display device clings to the light filter plate and voltages are applied to electrodes.

Description

Technical field [0001] The present invention relates to the field of display, in particular to a filter plate and a liquid crystal display device used in an IPS mode liquid crystal display panel. Background technique [0002] In recent years, with the rapid development of the information and communication field, there has been an increasing demand for various types of display devices. The current mainstream display devices mainly include: liquid crystal display device (LCD), plasma display device (PDP), electroluminescence display device (ELD) and vacuum fluorescent display device (VFD), etc. Because the liquid crystal display device has the advantages of lightness, thinness, small size, low power consumption, low radiation, etc., it is widely used in various data processing equipment, such as televisions, notebook computers, mobile phones, personal digital assistants, etc. The liquid crystal display device mainly includes: a TFT array substrate, a color filter plate, a liquid c...
