Abstract

The invention provides a liquid crystal display panel and a display device utilizing the same. The liquid crystal display panel comprises a first substrate, a second substrate, a liquid crystal layer and a half-wavelength-pattern phase difference film. The second substrate comprises a second electrode and a plurality of pixel areas, the second electrode includes a main part and a branch part, each pixel area includes a main pixel area and a sub pixel area, an included angle formed between a branch portion and main portion in the main pixel area is 45 degrees, and a pre-set angle between a branch portion and a main portion in the sub pixel area is not equal to 45 degrees. The half-wavelength-pattern phase difference film is glued on an outer lateral surface of the first substrate or the second substrate and comprises a zero-wavelength phase difference array and a half-wavelength phase difference array. By the aid of the above structure, the problems of color shift and penetration rate decrease of an existing liquid crystal display panel can be alleviated.

Description

【Technical field】 [0001] The invention relates to the field of liquid crystal display technology, in particular to a liquid crystal display panel and a display device for its application. 【Background technique】 [0002] Liquid Crystal Displays (LCDs) have been widely used in various electronic products. Most of the LCDs are backlight LCDs, which are composed of a liquid crystal display panel and a backlight module. A liquid crystal display panel is composed of two transparent substrates and a liquid crystal sealed between the substrates. [0003] Currently, a vertical alignment (Vertical Alignment, VA) technology has been developed for use in liquid crystal display panels. For example, a polymer stabilized vertical alignment (PSVA) liquid crystal display manufactured by a polymer-stabilized vertical alignment (PSA) process can have a wide viewing angle, a high aperture ratio, and a high Advantages such as comparison and simple manufacturing process. [0004] In PSVA liqui...
