Embodiment Construction

[0048] In-Plane Switching (IPS, In-Plane Switching) and Advanced Super Dimension Switching (ADS, Advanced Super Dimension Switch) modes are commonly used display modes for existing wide-angle LCD panels, also known as horizontal electric field LCD panels.

[0049] Take the ADS type LCD as an example for specific description, such as figure 1 As shown, the ADS type LCD includes an opposite substrate 104 and an array substrate 102 , and a liquid crystal layer 103 located between the opposite substrate 104 and the array substrate 102 . In order to ensure normal display, an upper polarizer 105 and a lower polarizer 101 whose light transmission axes are perpendicular to each other are arranged on the outer sides of the opposite substrate 104 and the array substrate 102 respectively. Since the liquid crystal cannot emit light, the liquid crystal display panel also needs to be provided with a backlight ( figure 1not shown). The light emitted by the backlight is emitted through the ...

Abstract

The invention discloses a display panel of a horizontal electric field type, a manufacturing method of the display panel, and a display device. A first compensation film layer is arranged between an opposite substrate and an array substrate, the sum of the phase difference of the first compensation film layer and the phase difference of a liquid crystal layer is integer multiple times of the wavelength of incident light, and the optical axis direction of the first compensation film layer is parallel to the initial optical axis direction of liquid crystal molecules in the liquid crystal layer.When optical anisotropy is generated by the opposite substrate and the array substrate under the condition of bearing uneven external force and the polarization state of permeating light is changed, the first compensation film layer can compensate for the phase delay of the polarization light passing through the liquid crystal layer, after light passes through the opposite substrate, the array substrate, the liquid crystal layer and the first compensation film layer, the total phase delay is nearly or equally integer multiple times of the wavelength of incident light, and light restores the original polarization state to a certain extent. In this way, in the dark state, most of light cannot emit out of the display panel, and the dark-state light leakage problem is solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a horizontal electric field display panel, a manufacturing method and a display device. Background technique [0002] Existing display devices mostly use liquid crystal (LCD, Liquid crystal display) display panels. When a horizontally oriented liquid crystal display panel realizes curved display in various ways, or when it is pressed under a force, it will more or less cause stress on the upper and lower substrates of the display panel, that is, the counter substrate and the array substrate, and then cause the substrate The base substrate produces optical anisotropy, and the polarization state of polarized light changes when it passes through the optically anisotropic base substrate, which will cause different degrees of light leakage in the dark state of the display panel. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a ...
