Liquid crystal display panel
First Claim
1. A liquid crystal display panel comprising:
- a pair of substrates arranged opposite to each other with a liquid crystal layer sandwiched therebetween,one of the pair of substrates includingplural scanning lines and signal lines arranged in a matrix state in a display area,a common wiring line formed along a peripheral edge portion of the display area,an interlayer resin film formed at least over the whole display area, anda lower electrode and an upper electrode made of a transparent conductive material arranged opposite to each other with an inter-electrode insulating film sandwiched therebetween,wherein the upper electrode includes plural slits formed in each pixel area sectioned in a row direction and a column direction by the scanning line and the signal line in the display area in planar view,wherein one of the upper electrode and the lower electrode is electrically connected to the common wiring line and operates as a common electrode,wherein in the display area, a common line is formed along the scanning line, the common line is made of a light shielding metal material, and the electrode operating as the common electrode is electrically connected to the common line through a contact hole in each pixel area, and the common line is electrically connected to the common wiring line at the peripheral edge portion of the display area,wherein the common line has a connection portion that is electrically connected to the electrode operating as the common electrode,wherein a width of the connection portion in the row direction is wider than a maximum width of the contact hole in the row direction, and a width of the connection portion in the column direction is wider than a maximum width of the contact hole in the column direction, andwherein the connection portion is formed at a position in which the connection portion overlaps with the contact hole in planar view so as to shield an opening of the contact hole.

Abstract
A liquid crystal display panel includes: substrates arranged opposite to each other with a liquid crystal layer therebetween. One of the substrates includes scanning and signal lines arranged in a matrix in a display area, a common wiring line along a peripheral edge portion of the display area, an interlayer resin film at least over the whole display area, and lower and upper electrodes arranged opposite to each other with an inter-electrode insulating film therebetween. The upper electrode includes slits in each pixel area sectioned by the scanning and signal lines. One of the upper and lower electrodes is formed over the whole display area and connected to the common wiring line and operates as a common electrode. In the display area, a common line is formed in parallel to the scanning line, the electrode operating as the common electrode is connected to the common line through a contact hole and the common line is connected to the common wiring line at the peripheral edge portion.
