Color film substrate and production method, display panel and display device of color film substrate

Abstract

The invention discloses a color film substrate and a production method, a display panel and a display device of the color film substrate used for solving the problems that a curve-flat conversion display panel leaks light or the transmittance is descended. The color film substrate comprises a substrate base plate, a black matrix and a color film layer including color sub pixels in matrix arrangement; the color film substrate also comprises a plurality of electrophoresis units and a flat layer; each electrophoresis unit comprises a first control electrode, a second control electrode, opaque charged particles, a transparent electrophoretic liquid medium and a transparent retaining wall; the transparent retaining wall is used for limiting the opaque charged particles and the transparent electrophoretic liquid medium in a first preset area; the area comprises the first control electrode and the second control electrode; the first control electrode and the second control electrode are respectively used for receiving different voltage signals to form a voltage difference, so that the opaque charged particles move towards the direction of the first control electrode or the second control electrode in a gathering way, and the width of a shading area between two adjacent color sub pixels is changed; the flat layer covers the whole substrate base plate and is used for sealing the electrophoresis units.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a color filter substrate and a manufacturing method thereof, a display panel, and a display device. Background technique [0002] With the development of display technologies, the requirements for liquid crystal displays (Liquid Crystal Display, LCD) are becoming more and more individualized and diversified. Taking a curved TV as an example, the relative positional relationship between the array substrate and the color filter substrate of the display panel (panel) will change slightly after bending, which will cause light leakage at the edge of the pixel, especially for a display panel with a large viewing angle. The phenomenon is more obvious. Therefore, in the prior art, when designing a curved panel, considering the problem of light leakage, it is generally necessary to design a non-uniform black matrix (Black Matrix, BM) or increase the width of the BM as a whole. ...
