Abstract

The invention discloses a liquid crystal display device. The liquid crystal display device comprises a TFT array substrate, and further comprises a back matrix, photo spacers, a CF substrate and a liquid crystal layer, wherein the TFT array substrate is provided with a first electrode layer and a first alignment layer covering the first electrode layer, a colorful film layer is formed between a glass substrate and a passivation layer of the TFT array substrate, the CF substrate is provided with a second electrode layer and a second alignment layer covering the second electrode layer, the liquid crystal layer is arranged between the first alignment layer of the TFT array substrate and the second alignment layer of the CF substrate, the preset alignment directions of the corresponding alignment areas of the first alignment layer and the second alignment layer are perpendicular to each other, and alignment films corresponding to the preset alignment directions of the alignment areas are formed on the first alignment layer and the second alignment layer. The invention further discloses a manufacturing method of the liquid crystal display device. According to the liquid crystal display device and the manufacturing method of the liquid crystal display device, the alignment effect is good, meanwhile, the large-visual-angle color cast can be improved, and the aperture opening ratio is improved.

Description

technical field [0001] The present invention relates to the field of manufacturing a thin film transistor liquid crystal display (Thin Film Transistor liquid crystal display, TFT-LCD), in particular to a liquid crystal display device and a corresponding manufacturing method. Background technique [0002] Such as figure 1 Shown is a schematic diagram of a pixel electrode commonly used in an existing PSVA mode (Polymer Stabilization Vertical-Alignment) liquid crystal display device; a pixel electrode is shown in the figure. In the existing liquid crystal display device of this PSVA mode, its pixel electrode is designed as a "meter" shape, consisting of a vertical trunk 80 in the middle, a horizontal trunk 81 and an included angle of ±45 degrees with the x-axis, ±135 Branch 82 of the degree consists of three parts. Among them, the vertical trunk 80 and the horizontal trunk 81 divide the pixel area into 4 areas on average, and each area is composed of 45-degree inclined branch...
