Embodiment Construction

[0032] Please refer to Figure 6 and Figure 7 . Figure 6 It is a sectional view of the first embodiment of the fringe electric field switching type liquid crystal display device of the present invention. The fringe electric field switching type liquid crystal display device 2 includes an upper substrate 270, a lower substrate 280, a liquid crystal layer 260, an upper alignment layer 273, a lower alignment layer 253, an insulating layer 251, a pixel electrode 240 and a common electrode 250. The substrate 270 is arranged opposite to the lower substrate 280, the liquid crystal layer 260 is located between the upper substrate 270 and the lower substrate 280, the alignment layers 273, 253 are respectively located on the upper substrate 270 and the lower substrate 280, and the common electrode 250 is a flat plate , located below the pixel electrode 240 as a whole, and the insulating layer 251 is located between the pixel electrode 240 and the common electrode 250 . In addition,...

Abstract

The invention discloses a LCD which comprises upper placode, lower placode, pixel electrode, common electrode, insulating inlay and at least one arranged inlay, wherein upper placode is arranged relatively with lower placode; the pixel electrode and common electrode are posited on the same placode; the common placode is planar plate-like; the insulating inlay is between pixel electrode and common electrode; the arranged inlay is on upper placode or lower placode and has first arranged direction and second arranged direction.

Description

【Technical field】 [0001] The invention relates to a liquid crystal display device, in particular to a fringe electric field switch type liquid crystal display device. 【Background technique】 [0002] The liquid crystal display device has many advantages such as low radiation, small and light volume, and low power consumption, so it is widely used day by day. However, when the user observes the liquid crystal display device from different angles, the contrast of the image will decrease with the increase of the viewing angle, thereby causing a viewing angle limitation. For grayscale and color displays, chromatic aberration and grayscale inversion also occur when the viewing angle is large. These weaknesses are particularly prominent when the liquid crystal display device is developed to a large size and can be watched by multiple people at the same time, which becomes a major obstacle to the challenge of the cathode ray tube (Celtic Retail Technology, CRT) technology. Therefo...
