Problems solved by technology

Since the opaque common line is parallel to the gate line, and the common line and the gate line are located on the same plane, the light-transmitting area in each pixel is reduced, so that the aperture ratio of the pixel is reduced, and the IPS panel low penetration

Embodiment Construction

[0035] Please refer to figure 1 , which shows a schematic cross-sectional view of a display panel and a backlight module according to an embodiment of the present invention. The in-plane switching (IPS) liquid crystal display panel 100 of this embodiment can be disposed on the backlight module 200 , thus forming an IPS liquid crystal display device. The IPS liquid crystal display panel 100 may include a first substrate 110 , a second substrate 120 , a liquid crystal layer 130 , a first polarizer 140 and a second polarizer 150 . The substrate material of the first substrate 110 and the second substrate 120 can be a glass substrate or a flexible plastic substrate. In this embodiment, the first substrate 110 can be, for example, a thin film transistor (Thin Film Transistor, TFT) matrix substrate, while the second The second substrate 120 can be, for example, a color filter (Color Filter, CF) substrate. It should be noted that, in some embodiments, the color filter and the TFT m...

Abstract

An in-plane switching (IPS) liquid crystal display panel and a method for manufacturing the same are disclosed. The method comprises the following steps: forming gate lines, data lines, common lines, pixel electrodes and common electrodes on a first substrate in sequence, wherein at least a portion of each of the common lines is positioned above each of the gate lines; and forming a liquid crystal layer between the first substrate and a second substrate. According to the invention, the aperture ratio of the pixels of the display panel can be improved.

Description

technical field [0001] The present invention relates to a liquid crystal display panel and a manufacturing method thereof, in particular to an in-plane switching (In Plane Switching, IPS) liquid crystal display panel and a manufacturing method thereof. Background technique [0002] As the information and communication industries continue to innovate, the liquid crystal display (Liquid Crystal Display, LCD) market is booming. Liquid crystal displays have the advantages of high image quality, small size, light weight, low driving voltage, and low power consumption, so they are widely used in personal digital assistants (Personal Digital Assistant, PDA), mobile phones, video recorders, notebooks, etc. Consumer communication or electronic products such as desktop computers, desktop monitors, car monitors, and projection TVs. [0003] Most of the liquid crystal displays are backlight liquid crystal displays, which are composed of a liquid crystal display panel and a backlight mo...
