Problems solved by technology

In the state of wide viewing angle, the sub-pixel electrode corresponding to the W sub-pixel is missing and does not participate in the display screen, resulting in a decrease in the aperture ratio of the pixel unit in the wide viewing angle state, resulting in a decrease in transmittance

Abstract

The invention provides a liquid crystal display panel, a manufacture method therefore, and a display device. The liquid crystal display panel is provided with a plurality of pixel units, wherein eachpixel unit comprises a first area and a second area; the first area is provided with a red sub-pixel electrode, a green sub-pixel electrode and a blue sub-pixel electrode; the second area is providedwith a white sub-pixel electrode; each pixel unit is also provided with a first common electrode and a second common electrode; each sub-pixel electrode and the first common electrode of the first area are positioned on different layers and are vertically arranged; the white sub-pixel electrode and the second common electrode of the second area are positioned on the same plane; and a color film substrate is provided with a visual angle control electrode by corresponding to the position of the white sub-pixel electrode. Through the liquid crystal display panel, the pixel unit is divided into the first area and the second area, during wide-visual-angle display, each sub pixel participates in picture display, during narrow-visual-angle display, the white sub-pixel electrode of the second areadoes not participate in picture display so as to realize consistent luminance and contrast ratio of the wide visual angle and the narrow visual angle, and meanwhile, the penetration rate of the wide-visual-angle display can be improved.

Description

technical field [0001] The invention relates to the field of display technology, and in particular to a liquid crystal display panel with switching between wide and narrow viewing angles, a manufacturing method thereof, and a display device. Background technique [0002] Liquid crystal display (liquid crystal display, LCD) has the advantages of good image quality, small size, light weight, low driving voltage, low power consumption, no radiation and relatively low manufacturing cost, and occupies a dominant position in the field of flat panel display. [0003] Currently, liquid crystal display devices are gradually developing toward wide viewing angles. For example, liquid crystal display devices using in-plane switching (IPS) or fringe field switching (FFS) modes can achieve wider viewing angles. The wide viewing angle design allows users to see a complete and undistorted picture from all directions. However, in today's society, people pay more and more attention to protec...
