Embodiment 1

[0038] like Figure 1 to Figure 6 As shown, a liquid crystal display panel provided by the first embodiment of the present invention includes a first substrate 10 , a second substrate 20 disposed opposite to the first substrate 10 , and a liquid crystal layer located between the first substrate 10 and the second substrate 20 30. On the side facing the liquid crystal layer 30 of the second substrate 20, a plurality of scanning lines 1 and a plurality of data lines 2 are mutually insulated and intersected to form a plurality of pixel units P, and each pixel unit P is provided with a pixel electrode 23 and a The thin film transistor 3, the pixel electrode 23 is electrically connected to the scan line 1 and the data line 2 adjacent to the thin film transistor 3 through the thin film transistor 3, wherein the first substrate 10 is a color filter substrate, the second substrate 20 is an array substrate, and the thin film transistor 3 It includes a gate electrode, a source electrode ...

Embodiment 2

[0053] like Figure 7 As shown, the liquid crystal display panel provided by the second embodiment of the present invention is the same as that of the first embodiment ( Figure 5 ) are basically the same as the liquid crystal display panels in In the first wave plate 26 , the fast and slow axes of the second quarter wave plate 26 and the second light transmission axis X2 of the second polarizer 50 are at 45°. Because, using the entire first quarter-wave plate 13, it is necessary to attach the second quarter-wave plate 26 on the second substrate 20 side corresponding to the first quarter-wave plate 13, so as not to affect the transmission Normal display of zone T. Of course, the second quarter wave plate 26 only needs to correspond to the transmission region T, but this will increase the etching process.

[0054] In this embodiment, the first quarter-wave plate 13 is disposed between the first substrate 10 and the auxiliary electrode 14 , and the second quarter-wave plate 2...

Embodiment 3

[0058] like Figure 8 As shown, the liquid crystal display panel provided by the third embodiment of the present invention is the same as the second embodiment ( Figure 7 ) is basically the same as the liquid crystal display panel in The wave plate 26 is arranged between the second substrate 20 and the second polarizer 50. Of course, the first quarter wave plate 13 and the second quarter wave plate 26 can also be arranged in other layers according to actual requirements, for example , the first quarter-wave plate 13 is arranged between the first substrate 10 and the color resist layer 11 , and the second quarter-wave plate 26 is arranged between the second substrate 20 and the common electrode 21 . limited.

[0059] Compared with the second embodiment, in this embodiment, the first quarter-wave plate 13 is disposed outside the liquid crystal cell, that is, on the side of the first substrate 10 away from the liquid crystal layer 30 , which can reduce the difficulty of the ma...

Abstract

The invention discloses a liquid crystal display panel, comprising a first substrate, a second substrate opposite to the first substrate, and a liquid crystal layer located between the first substrate and the second substrate, and a first polarizer is arranged on the first substrate , the second substrate is provided with a second polarizer, the first substrate is provided with a first quarter-wave plate, and the fast and slow axes of the first quarter-wave plate are in the same shape as the first transmission axis of the first polarizer. 45°, reflective electrodes are provided on the second substrate, and auxiliary electrodes opposite to the reflective electrodes are provided on the first substrate. The area of ​​the liquid crystal display panel corresponding to the reflective electrode is the reflective area, and the area of ​​the liquid crystal display panel corresponding to each pixel unit is the transmissive area. area, the thickness of the liquid crystal layer corresponding to the reflective area is half of the thickness of the liquid crystal layer corresponding to the transmissive area. Switching between specular reflection and transmission is achieved by controlling the corresponding liquid crystal molecules in the reflection area to switch between lying down or standing postures. The invention also discloses a driving method and a liquid crystal display device.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, and in particular, to a liquid crystal display panel, a driving method thereof, and a liquid crystal display device. Background technique [0002] With the development and progress of liquid crystal display technology, people have higher and higher requirements for liquid crystal display devices. At present, a display device that can be used as a mirror and has a display function is very popular, that is, a mirror display device. [0003] The preparation of the existing mirror display device usually adopts a layer of semi-reflective and semi-transmissive film on the surface light of the display panel. When displaying, the light from the backlight passes through the display panel to form a color picture for display; when the display is completed After that, the mirror display can be realized when the light from the external environment is irradiated on the semi-reflective an...
