Problems solved by technology

[0005] At present, the method for solving the above-mentioned problems is mainly by adjusting the uniformity of the height of the substrate spacer (CN102778788A), changing the contact mode of the spacer (CN103969892A) or changing the material of the parts (CN204331233U), but these methods have complicated procedures and high costs. Difficult to apply in actual production

Embodiment 1

[0022] According to the liquid crystal weight M and the substrate area S shown in Table 1, the liquid crystal is injected into two equal-area glass substrates (one of which has a TFT element on the glass substrate), and the bubble generation rate (%) of the obtained liquid crystal display device is tested. and marginal mura incidence (%), the results are shown in Table 1.

Abstract

The invention discloses a liquid crystal display device. The liquid crystal display device comprises two substrates and a liquid crystal material clamped between the two substrates. A TFT (thin film transistor) element is arranged on one of the substrates, and a mass M of the liquid crystal material and an area S of the substrates are in a numerical value relationship that S / 10000<M<S / 2000, wherein a unit of S is square centimeter, and a unit of M is gram. The liquid crystal display device has advantages that by control of a ratio relationship between the liquid crystal mass and the substrate area, the bubble occurrence rate and the margin mura occurrence rate can be effectively decreased, great display effects can be achieved, and high operability, low cost and high practicality are realized.

Description

technical field [0001] The invention relates to the field of liquid crystal display devices, in particular to a liquid crystal display device with low bubble generation rate and good display. Background technique [0002] Liquid crystal display is a commonly used flat-panel display at present. At present, thin film transistor liquid crystal display (TFT-LCD, Thin Film Transistor-Liquid Crystal Display) has become the mainstream of liquid crystal display due to its low weight, low power consumption, high definition, passive luminescence and many other advantages. Products are widely used in electronic display products such as mobile phones, computers, and televisions. With the continuous improvement of people's awareness level and realistic requirements, the display quality of liquid crystal displays has been paid more and more attention by people. Among them, vacuum bubbles and edge mura are common display defects, which seriously affect the quality of products and affect th...
