Embodiment Construction

[0014] see figure 1 , is a schematic plan view of the primary pixel unit of the first embodiment of the active matrix liquid crystal display device of the present invention, and the active matrix liquid crystal display device is a reflective active matrix liquid crystal display device. The sub-pixel unit 1 includes two adjacent data lines 11 and 12 arranged vertically, two adjacent gate lines 13 and 14 arranged horizontally, a pixel electrode 15 and a thin film transistor (not shown).

[0015] A primary pixel electrode area is formed between the data lines 11, 12 and the gate lines 13, 14, and the pixel electrode 15 is a reflective electrode, which is arranged in the pixel electrode area and partially covers the corresponding data lines 11, 12 and The gate lines 13, 14, such as figure 1 Shown in the shaded part. Of course, the pixel electrode 15 can also be only disposed in the pixel electrode area without covering the corresponding data lines 11 , 12 and the gate lines 13 ,...

Abstract

A drive matrix type liquid crystal display apparatus, it comprises a second pixel unit, the second pixel unit comprises two data wires which are adjacent and end-to-end set-up, tow grating wires which are adjacent and transverse arrangement, a pixel electrode and a thin film transistor. The two data wires and tow grating wires form a second pixel electrode area; the pixel electrode is placed on the second pixel electrode area. The thin film transistor is provided with a source, a grating, a drain; the three is linked to the corresponding data wires, grating wire, and pixel electrode separately. Wherein, the data wires and the grating wire are anti-reflection films.

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] Liquid crystal display devices can usually be divided into passive matrix type and active matrix type according to their different driving methods. Among them, the active matrix type liquid crystal display device has the advantages of fast response speed, various colors and high contrast, and has become one of the mainstream of current liquid crystal display devices. . [0003] In the prior art, active matrix liquid crystal display devices can be classified into reflective, transmissive and transflective active matrix liquid crystal display devices according to their light utilization methods. Although they use light in different ways, they all use thin film transistors as the control unit of the pixel electrodes to achieve active display. [0004] Generally, a pixel unit of an active matrix liqu...
