Wide-angle liquid crystal display panel

Abstract

This invention discloses a wide-angle LCD face plate, including the first compensational base plate that has the first surface and the second surface; the first direction-matching film that is on the first surface; the first polarizing plate on the second surface; the second compensational base plate that has the third and the forth surfaces; the second direction-matching film on the third surface; the second polarizing plate on the forth surface; and a LCD molecule layer, and the first and the second compensational base plates are matched at the opposite positions of the first and the third surfaces, and the LCD molecule layer is between the first and the second compensational base plates. This invention can decrease the manufacturing processes and reduce the cost, and also the thickness of the face plate and improve the optic performance.

Description

technical field [0001] The invention relates to a liquid crystal display panel, in particular to a liquid crystal display panel with a wide viewing angle. Background technique [0002] Active Thin Film Transistor (TFT-LCD) is a component used to actively control the amount of light passing through each pixel (pixel), and its image generation is to allow each independent pixel on the panel to produce the desired color. To achieve this, multiple cold-cathode lamps must be used as the backlight for the display, and in order to allow light to pass through each pixel, the panel must be segmented and made into small doors or switches to allow light to pass through. Liquid crystal displays (LCDs) are light-modulating screens that use liquid crystal components. Liquid crystals can change their molecular structure so that they can let varying amounts of light pass through them (or block light entirely). The liquid crystal display contains two polarizers, a color filter array and an ...

Problems solved by technology

Because liquid crystal displays use the characteristics and optical properties of liquid crystals between solid and liquid, and use optical films to display light and shade. The combination of various optical films will affect the final display quality

However, only Fuji Photo (Nissho) in the world currently provides optical compensation films that increase the viewing angle contrast of TFT-LCD. The wide-viewing angle film (FujiFilm) produced by Fuji Photo is provided to polarizing film manufacturers, and the polarizing film manufacturers are bonded and then sold. Selling to TFT-LCD manufacturers, the price is 2 to 3 times that of polarizing film without wide viewing angle film, which not only increases the cost and prolongs the production time, but also due to the uneven quality of the wide viewing angle film attached by various polarizing film manufacturers, Therefore, when combining polarizing films from different manufacturers, it is easy to cause the problem of lower yield
