Embodiment 2

[0057] figure 2 is a schematic plan view of the array substrate in Embodiment 2 of the present invention, Figure 9 It is a schematic plan view of the color filter substrate in Embodiment 2 of the present invention. Such as Figure 9 As shown, the display panel provided by Embodiment 2 of the present invention is the same as Embodiment 1 ( Figures 1 to 7 The display panels in ) are basically the same, the difference is that in this embodiment, a plurality of blank areas P2 are arranged along the lateral direction, that is, along the extending direction of the scanning line 1 ( figure 2 ), the viewing angle control electrode 131 is a strip electrode extending along the lateral direction and covers a whole row of a plurality of blank areas P2. Every two rows of color regions P1 correspond to a row of blank regions P2 in a periodic arrangement. Of course, in other embodiments, three rows of color regions P1 correspond to a row of blank regions P2 in a periodic arrangement, ...

Abstract

The invention discloses a display panel, comprising a color film substrate, wherein the color film substrate is provided with a plurality of color areas, a plurality of blank areas and black matrixes,the black matrixes are used for separating the plurality of color areas from each other, separating the plurality of blank areas from each other, and separating the color areas from the blank areas,the color area is provided with a color resistance material therein, the blank area is in a transparent state, the color film substrate is also provided with a visual angle control electrode layer, the visual angle control electrode layer comprises a plurality of visual angle control electrodes covering the blank areas, and the visual angle control electrodes are directly formed on the surface ofthe color film substrate. According to the display panel of the invention, the visual angle control electrodes are directly formed on the surface of the color film substrate, so that the surfaces of the visual angle control electrodes are smooth, and a vertical electric field is formed by the visual angle control electrodes with public electrodes at the side of an array substrate, thereby improving a contrast ratio, in addition, wide / narrow visual angle switching is only achieved at the blank areas, thereby reducing gray scale reversal under a large visual angle. The invention also discloses adisplay device and a manufacturing method of the display panel.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display panel, a manufacturing method and a display device. 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. Toggle function. [000...
