Liquid crystal display device

Abstract

The invention provides a liquid crystal display device, which comprises a first substrate, a second substrate and a liquid crystal layer sandwiched between the first substrate and the second substrate, wherein the side, facing the liquid crystal layer, of the first substrate is provided with a functional membrane layer which has a plurality of convex parts and / or concave parts and also provided with a flattened medium layer covering the functional membrane layer and a metal reflecting layer on the flattened medium layer. The functional membrane layer comprises one or more than two of a gate metal layer, a gate insulated layer, a semiconductor layer, a source-drain metal layer and an insulated protective layer. The liquid crystal display device and the manufacturing method thereof can avoid single-angle mirror reflection of a smooth plane to improve the reflectivity of diffuse reflection and expand a reflection view angle. In addition, compared with technology for improving backlight brightness, the method can ensure high visuality of a liquid crystal display used indoor and outdoor in the sun without increasing the overall power consumption of the liquid crystal display.

Description

technical field [0001] The invention relates to the field of flat panel display technology, in particular to a liquid crystal display device and a manufacturing method thereof. Background technique [0002] As a flat panel display, liquid crystal display (LCD) has many advantages such as clear and accurate image, thin thickness, light weight, no radiation, low energy consumption and low working voltage, and has been widely used in various fields. Generally, a liquid crystal display has two substrates containing electrodes, and a liquid crystal layer arranged between the two substrates. The electric field intensity applied to the liquid crystal layer is controlled by the electrodes on the two substrates to control the deflection of the liquid crystal molecules, thereby adjusting the intensity of the incident light. Transmittance, in order to control the brightness and darkness of display pixels. [0003] Thin Film Transistor (TFT) liquid crystal displays are used more and mo...

AI Technical Summary

Problems solved by technology

[0004] Ordinary fully transparent TFT liquid crystal displays cannot meet the above requirements. When used outdoors, due to the strong reflection of sunlight, it is necessary to increase the surface brightness of the TFT liquid crystal display, or make a layer of material on the surface of the TFT display to reduce reflected light. Has good visibility and meets the requirements for outdoor use

Generally speaking, the only way to increase the surface brightness is to increase the brightness of the backlight of the TFT liquid crystal display. However, the increase in the brightness of the backlight of the TFT liquid crystal display increases the overall power consumption of the device and puts forward higher requirements for the power supply system of the device, such as mobile phones. , it is necessary to use high-energy batteries to meet the requirements of use
