Color film substrate and display device

Abstract

The invention discloses a color film substrate and a display device. The color film substrate comprises a substrate base plate, a black matrix and a common electrode, wherein the common electrode is arranged on one side, away from the substrate base plate, of the black matrix which is formed on the substrate base plate. At least one first metal wire is arranged in a shading area, corresponding to the black matrix, in a display area of the color film substrate and is connected with a common voltage input end, and a plurality of points on each first metal wire are electrically connected with the common electrode. After the color film substrate and an array substrate are connected through a golden ball doped frame seal adhesive, a common electrode wire of the array substrate can be communicated with the first metal wires on the color film substrate by golden balls, voltages in different areas of the common electrode of the color film substrate can be transmitted and inputted by the at least one first metal wires, and accordingly voltage uniformity of the common electrode of the color film substrate is guaranteed, and defects of flickering, crosstalk, nonuniformity and the like of frames displayed by a display panel are overcome.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a color filter substrate and a display device. Background technique [0002] In the existing liquid crystal display device, the common electrode on the color filter substrate and the common electrode line on the array substrate have the same voltage, but the voltage of the common electrode on the color filter substrate is not powered independently, and needs to be uploaded from the common electrode line on the array substrate. Therefore, it is necessary to conduct the common electrode on the color filter substrate and the common electrode line on the array substrate. [0003] Please refer to figure 1 , in the existing color filter substrate, usually after the black matrix 02 and the color filter layer 03 are formed on the base substrate 01, the color filter substrate common electrode 04 is directly formed on the black matrix 02, so that the color filter substrate and th...

Problems solved by technology

[0004] However, at present, the common electrode of the color filter substrate is usually made of indium tin oxide (ITO). For a larger-sized display panel, a larger-sized common electrode needs to be provided, which will easily cause the voltage across the common electrode to vary. Even, the screen displayed by the display device has different degrees of flickering, crosstalk, and uneven screen, which seriously affects the display effect of the display device and the product qualification rate.
