Abstract:
1. A liquid crystal display apparatus, comprising: an array substrate comprising a pixel electrode disposed to each of display pixels disposed in a matrix state, a gate line and an auxiliary capacitance line extending along a row along which the pixel electrode is arranged, a signal line extending along a column along which the pixel electrode is arranged, a semiconductor that intersects the gate line via a first insulating layer and confronts the auxiliary capacitance line, a contact electrode configured to electrically connect the semiconductor to the pixel electrode, and a drive circuit for driving the gate line, the signal line, and the auxiliary capacitance line; a counter substrate disposed in confrontation with the array substrate; and a liquid crystal layer sandwiched between the array substrate and the counter substrate, wherein, in the display pixels disposed side by side in a direction where the gate line extends, the positions of center of gravity of openings of the display pixels, in which the openings of the display pixels include at least the pixel electrode, a second insulating layer which is formed on the first insulating layer, and a third insulating layer which is formed on the second insulating layer within, surrounded by the gate line, the signal line, the auxiliary capacitance line, and ends of the contact electrode are the same in a direction where the signal line extends, the shapes of the openings are placed in line symmetry with respect to the gate line, each of the openings comprises a first opening on one side of the gate line in the direction where the signal line extends and a second opening on the other side of the gate line, the auxiliary capacitance line comprises a convex portion projecting in the direction where the signal line extends, the first opening is formed in a concave shape surrounded by the gate line, the signal line, the auxiliary capacitance line, and the end of the contact electrode, and the second opening is formed in a concave shape surrounded by the gate line, the signal line, and an end of the auxiliary capacitance line including the convex portion.
