Patent ID: 8259279

Claim:
A liquid crystal display panel comprising: a first substrate; a second substrate; and a liquid crystal layer interposed between the first and second substrates, the first substrate including a first insulating substrate, a first wiring, and a flattening layer, the first wiring being formed on a liquid crystal layer side of the first insulating substrate, the flattening layer being arranged between the liquid crystal layer and the first wiring, the second substrate including a second insulating substrate and a column spacer, the column spacer being arranged on a liquid crystal layer side of the second insulating substrate to face a region where the first wiring overlaps with the flattening layer, wherein the first substrate includes a height adjustment layer, the height adjustment layer being arranged to face the column spacer, and wherein the first substrate includes a pixel electrode and the height adjustment layer satisfies the following formula (1): 0 <z< 2×( x−y ) (1) in the formula (1), z representing a thickness of the height adjustment layer, x representing (h 1 −dp): a difference between h 1 and dp, the h 1 representing a height of the first wiring from a surface of the first insulating substrate in a region facing the column spacer, the dp representing a thickness of the pixel electrode, y representing (h 2 −h 3 −z): a value calculated by subtracting h 3 and z from h 2 , the h 2 representing a height of a top surface from the surface of the first insulating substrate in a region where the height adjustment layer is arranged, the h 3 representing a height of the top surface from the surface of the first insulating substrate in a region facing a pixel opening, the z representing a thickness of the height adjustment layer.
