Abstract
The generation of bubbles in a liquid crystal material of a liquid crystal display panel and the generation of color irregularities when the liquid crystal display panel is pushed can be reduced. In a display device having a liquid crystal display panel in which a liquid crystal material is filled between a first substrate and a second substrate, the second substrate forms, on a surface of an insulation substrate which faces the first substrate, first columnar members, second columnar members and third columnar members which differ from each other in a distance from the surface of the insulation substrate to a top portion of each columnar member. Assuming the distance of the first columnar member as L, the distance of the second columnar member as Land the distance of the third columnar member as L, a relationship among the distances L, L, Lsatisfies L>L>L, and assuming the number of the first columnar members arranged on the surface of the insulation substrate as N, the number of the second columnar members arranged on the surface of the insulation substrate as Nand the number of the third columnar members arranged on the surface of the insulation substrate as N, a relationship among the numbers N, N, Nsatisfies N>N>N
