Liquid crystal display having bloom backing liner integrated plastic base plate

Abstract

A liquid crystal display device applied to a terminal with a mobile function. The device is used to prevent the machine from being damaged due to falling when moving, and uses plastic as the substrate material. In this device, at least one lower substrate and upper substrate made of plastic material and having liquid crystal driving electrodes are connected by means of a liquid crystal layer, and polarizers are attached to the back of each substrate. Pad, the above-mentioned pad is a pillar pad integrally made with the substrate. Here, the pillar spacer is fabricated integrally with only an optional one of the plastic lower substrate or the plastic upper substrate, or is integrally fabricated with all of the plastic lower substrate and the plastic upper substrate. The pillar spacer has a height of a plate gap ±α, the plate gap is set at 0.2 to 10 μm, and α is 1 μm or less.

Description

technical field [0001] The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device capable of preventing degradation of picture quality caused by uneven distribution of spacers in a liquid crystal display device using a plastic substrate. Background technique [0002] With the development of wireless mobile communication, liquid crystal display devices are widely used as information display devices of communication terminals. At the same time, due to various consumer requirements such as high picture quality, high information processing, light weight, and prevention of damage to the glass substrate due to falling of the device when moving, the research and development of the mobile terminal For example, in order to solve the problem of damaging the glass substrate when the machine falls when moving, the substrate material of the mobile terminal is changed from glass to plastic. [0003] Here, thin film transist...

Problems solved by technology

[0007] However, in the case of a liquid crystal display device in which a plastic substrate is used and spherical spacers are distributed, the plastic substrate is sometimes bent or rolled up like paper because the above-mentioned plastic substrate has a flexible characteristic. At this time, the spherical spacer Of course it moves to an arbitrary position, resulting in pad clumping in the active area, so when driven in greyscale, there is a problem of uneven brightness on specific tones
