Embodiment Construction

[0016] see image 3 and Figure 4 , image 3 It is a structural schematic diagram of a pixel unit 200 of an in-plane lateral electric field switching liquid crystal display of the present invention, Figure 4 is along image 3 Sectional view along line IV-IV shown. The in-plane lateral electric field switching liquid crystal display includes a first substrate 230 , a second substrate 240 and a liquid crystal layer (not shown) sandwiched between the first substrate 230 and the second substrate 240 . The pixel unit 200 includes a data line 201 , a gate line 202 , a common electrode 210 , a pixel electrode 211 , a shielding metal line 212 and a thin film transistor 205 . The data line 201 intersects with the gate line 202 and is disposed on the first substrate 230 to define the range of the pixel unit 200 . The shielding metal line is disposed on both sides of the data line 201 to prevent light leakage at the edge of the pixel unit 200 . The thin film transistor 205 is arra...

Abstract

The invention relates to a transverse electric field switching type liquid crystal display inside the plate, wherein it comprises: one first substrate, one second substrate, and the liquid crystal layer between first and second substrates, one shield metal line above the first substrate, one first insulated layer above the shield metal line, one leakage wire above the first insulated layer, one second insulated layer above the leakage line, and one public electrode above the second insulated layer; and the leakage line is between the shield metal line and the public electrode. The invention has high open rate.

Description

【Technical field】 [0001] The invention relates to an in-plane transverse electric field switching liquid crystal display. 【Background technique】 [0002] At present, the liquid crystal display has gradually replaced the traditional cathode ray tube (Cathode Ray Tube, CRT) display used in the computer, and because the liquid crystal display is light, thin, and small, it is very suitable for use in desktop computers, laptops, etc. In computer, personal digital assistant (Personal Digital Assistant, PDA), portable phone, TV and various office automation and audio-visual equipment. [0003] The liquid crystal in the liquid crystal display itself does not have luminescent properties, and it uses an electric field to control the twisting of the liquid crystal molecules to realize the passage or non-passage of light, so as to achieve the purpose of display. In a traditional twisted nematic (TN) liquid crystal display, electrodes are formed on the surfaces of two glass substrates t...
