A liquid crystal display panel, manufacturing method thereof, and display device

Abstract

The invention discloses a liquid crystal display panel and a manufacture method and a display device thereof. The manufacture method of the liquid crystal display panel mainly comprises the steps that through the arrangement of at least one groove in the side, close to an array substrate, of a color film substrate, each groove corresponds to a cross bridging structure formed by the overlapping of any two metal wires in an insulation mode in the array substrate, each cross bridging structure can be covered with the vertical projection, in the array substrate, of the corresponding groove, and the depth, in the direction perpendicular to the direction of the array substrate, of each groove is not less than the height of the corresponding cross bridging structure. Therefore, the spacing of an air gap, located on the position where cross bridging structures exist, between the array substrate and the color film at the opposite side is in accordance with the spacing of an air gap formed in the position where cross bridging structures do not exist, enough containing space of a transparent pad in the position is guaranteed, the serious extrusion on the cross bridging structures can not occur during alignment fitting, the short circuit of an upper metal wire and a lower metal wire on each cross bridging structure is avoided, and therefore the yield of the liquid crystal display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel, a manufacturing method thereof, and a display device. Background technique [0002] In the existing liquid crystal display panel, especially for the liquid crystal display panel with a narrow frame design, in order to save the wiring space, various metal wires may be arranged in the frame area of ​​the array substrate 1a, or even two metal wires (metal wires 1b and the metal line 1c) are insulated and overlapped to form a cross bridging structure 1d. Such as figure 1 As shown, when the sealant doped with transparent liner 1e is coated on the frame area, and the upper and lower substrates are aligned and bonded, the transparent liner may just be located at the cross-over structure. The existence of the bridging structure makes the space between this position and the opposite substrate 1f smaller, and the volume of the transparent liner is small, ...
