Problems solved by technology
However, this will cause the refractive index of each area to be different, causing the optical film to scatter and not effectively achieve the transparent effect
Therefore, for the window type LCD display, it can only be used in the design with a light box, but cannot be used in applications without a light box

The invention provides a liquid crystal display comprising an upper substrate, a lower substrate, a liquid crystal layer, a first polarizing film and a second polarizing film. The lower substrate and the upper substrate are correspondingly arranged; the liquid crystal layer is arranged between the upper substrate and the lower substrate; the first polarizing film is located above the upper substrate; the second polarizing film is located below the upper substrate; liquid crystals of the liquid crystal layer are in vertical arrangement, the absorption axis of the first polarizing film is parallel to that of the second polarizing film. By adopting the invention, the liquid crystal display is vertically arranged and matched with a normal white mode; when displaying a bright state, liquid crystal molecules are arranged vertically, refractive indexes in all areas are consistent, the optical scattering can not be caused, and a better transparency effect can be achieved.
Description
technical field [0001] The invention relates to a liquid crystal display, in particular to a liquid crystal display with better transparent effect. Background technique [0002] At present, liquid crystal displays (LCDs) are developing towards the trend of increased display capacity, high brightness, high contrast ratio, large viewing angle, large area and full color. A multi-domain vertical alignment (MVA for short) technology can be used to increase the viewing angle of the liquid crystal display. For large-size panels, the combination of multi-area vertical alignment (MVA) mode and normally black display mode (Normally Black display mode) is often used, that is, the liquid crystal molecules in the initial state are arranged vertically, because the polarizers are perpendicular to each other, and the light from a polarizer at this time After passing through, it cannot pass through the other polarizer, and the screen is black. When a voltage is applied, the liquid crystals...
