Please combine Figure 8 to Figure 9 The difference between this embodiment and the first embodiment is that the aperture ratio of each sub-pixel unit 100 is equal, that is, the light-transmitting area of ​​each sub-pixel unit 100 is equal, and the viewing angle control voltage signal is applied to the array through the third metal layer 109 The middle of the viewing angle control electrode 121 on the substrate 10 , that is, the viewing angle control voltage signal is not input from one end of the viewing angle control electrode 121 . When the viewing angle control voltage signal is applied to the middle of the viewing angle control electrode 121, along the gate line 102 (refer to Figure 8 ) extends toward both ends, and the resi...

[0060] Figure 10 It is a schematic plan view of the array substrate in the third embodiment of the present invention. Please combine Figure 10 The difference between this embodiment and the first embodiment is that, along the direction parallel to the gate lines 102, each row of viewing angle control electrodes 121 is divided into at least three regions, and the viewing angle control electrodes 121 near the middle of the liquid crystal display panel are applied The viewing angle control voltage signal is greater than the viewing angle control voltage signal applied to the viewing angle control electrode 121 away from the middle of the liquid crystal display panel. That is to say, starting from the middle of the liquid crystal display panel and extending toward both ends along the direction of the gate lines 102 , the electric field in the viewing angle control region 100 b gradually decreases.

Abstract

The invention provides an array substrate, a color filter substrate, a liquid crystal display panel and a manufacturing method of the liquid crystal display panel. The liquid crystal display panel is provided with a plurality of sub-pixel units formed by intersections of data lines and gate lines, each sub-pixel unit includes a display area and a viewing angle control area; each display area includes two first sub-pixels, each viewing angle control area The area includes the second sub-pixel, and under the narrow viewing angle, along the direction from the middle to both sides of the gate line of the liquid crystal display panel, the oblique light leakage of the sub-pixel unit gradually decreases. In the present invention, a display area and a viewing angle control area are arranged on each sub-pixel unit, and a viewing angle control electrode is arranged on an array substrate. Under narrow viewing angles, by changing the voltage on the viewing angle control electrode or changing the The light transmission area of ​​the liquid crystal display panel is changed to change the oblique light leakage of the liquid crystal display panel at a narrow viewing angle, thereby reducing the production cost and improving the display quality of the display panel at a narrow viewing angle.

Description

technical field [0001] The invention relates to the field of display technology, and in particular to a liquid crystal display panel and a manufacturing method of the liquid crystal display panel. Background technique [0002] With the continuous advancement of liquid crystal display technology, the viewing angle of the display has been expanded from about 120° to more than 160°. While enjoying the visual experience brought by the large viewing angle, people also hope to effectively protect commercial secrets and personal privacy. Avoid commercial loss or embarrassment caused by information leakage on the screen. [0003] The current display devices are gradually developing in the direction of wide viewing angles. Whether it is a mobile terminal application, a desktop display or a notebook computer application, in addition to the demand for a wide viewing angle, in many occasions, the display device is also required to have a wide viewing angle and a narrow viewing angle.
