Active matrix type liquid crystal display device

Abstract

This invention relates to an active matrix LCD device, which comprises the following: first base and second base; one LCD layer located between the first and second bases and multiple picture element units on the second base, wherein the picture element unit comprises the common electrode parallel located and picture element electrode and the isolation layer located between the common electrode and picture element electrode. It adopts the common electrode and picture element electrode to generate two vertical electric fields parallel to the two base electric field when on voltage and under two fields action, the LCD molecules can make their vertical directions to enlarge the vision angles of two directions.

Description

【Technical field】 [0001] The invention relates to a liquid crystal display device, in particular to an active matrix liquid crystal display device. 【Background technique】 [0002] The liquid crystal in the liquid crystal display device itself does not have luminescent properties, and the liquid crystal molecules are twisted by using an electric field to realize the passage or non-passage of light, thereby achieving the purpose of display. In a traditional liquid crystal display device, electrodes are formed on the surfaces of two glass substrates to form an electric field that controls the twisting of liquid crystal molecules. The electrodes use transparent conductive materials, and the electrodes of the two substrates are oppositely arranged to form an electric field perpendicular to the substrate surfaces. Since the liquid crystal molecules have positive conductance anisotropy, under the control of the electric field, the orientation of the liquid crystal molecules will be...

Problems solved by technology

[0008] When a voltage is applied, the common electrode 15 and the pixel electrode 16 can only form an electric field 18 parallel to the first substrate 11 and the second substrate 12 in a certain direction, and the liquid crystal molecules 171 are affected by the electric field 18, and their long axes can only be aligned in the The direction of the electric field 18, thus, the viewing angle in the direction of the electric field 18 is enlarged; however, since the liquid crystal molecules 171 are only oriented in the direction of the electric field 18, thus, in the direction perpendicular to the electric field 18, the viewing angle has not been improved yet , so the liquid crystal display device 1 still has a certain viewing angle defect
