Problems solved by technology

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 substrate, which will cause different degrees of light leakage in the dark state of the display panel.

Embodiment Construction

[0062] 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.

[0063] 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 1 not shown). The light emitted by the backlight is emitted through the...

Abstract

The invention discloses a horizontal-electric-field-type display panel, a production method thereof and a display device. A first compensation membrane is arranged between an opposite substrate and anarray substrate, and when the display panel is subjected to uneven external force, phase delay of axial light ray is compensated for. In this way, under the condition that the opposite substrate andthe array substrate are subjected to uneven external force, the optical aeolotropy is generated, when the polarization state of the penetration light ray is changed, the first compensation membrane can compensate for phase delay of polarized light when the light passes through a liquid crystal layer, and after passing through the opposite substrate, the array substrate, the liquid crystal layer and the first compensation membrane, the light ray is restored to the original polarization state to a certain degree. In this way, under the dark state, most light ray cannot be emitted from the display panel, and accordingly the light leakage problem under the dark state 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 ...
