Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art based on this application belong to the scope of protection of this application.

[0049] At present, displays using the ADS display mode have many advantages such as high resolution, low power consumption, wide viewing angle, and high aperture ratio. Such as figure 1Shown is a schematic diagram of a pixel unit 120 of an ADS display mode display in the related art. The pixel unit 120 includes a thin film transistor 130 , a base substrate 110 , a common electrode 150 , a pixel electrode 140 and other components, such as a protective layer 160 and the like. figure 1 The...

Abstract

The embodiment of the invention provides a display panel, a manufacturing method thereof and a display device. The display panel comprises a substrate base plate and a plurality of pixel units arranged on the substrate base plate. Each pixel unit comprises a thin film transistor, a pixel electrode connected with the thin film transistor, and a common electrode arranged opposite to the pixel electrode in the thickness direction of the display panel; the display panel further comprises a protective layer covering the thin film transistor, and the protective layer is arranged between the pixel electrode and the common electrode. One of the common electrode and the pixel electrode comprises a plurality of strip-shaped sub-electrodes, a groove is formed in the surface of the side, away from the thin film transistor, of the protection layer, and the strip-shaped sub-electrodes are arranged on the side wall of the groove. According to the embodiment of the invention, the strip-shaped sub-electrodes in the pixel units are arranged on the side walls of the protection layers, so that the aperture ratio of the pixel units is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the development of display manufacturing technology, display technology develops rapidly, for example, LCD (Liquid Crystal Display) display and OLED (Organic Light-Emitting Diode) display. [0003] Among them, the ADS (advanced super dimension switch technology, ADvanced Super Dimension Switch, referred to as ADS) display mode TFT display has many advantages such as high resolution, low power consumption, wide viewing angle, and high aperture ratio. [0004] In the related art, in the display using the ADS display technology, the common electrode and the pixel electrode of the pixel units in the display panel are insulated from each other, and one of them is formed on the surface of the protective layer by photolithography. Although the light transmittance of the ...
