PROBLEM TO BE SOLVED: To provide such technology that columnar spacers can be formed similar to columnar spacers having a plurality of heights.SOLUTION: A liquid crystal display device includes a first insulating substrate and a second insulating substrate, where a first pixel 301, a second pixel 302 and a third pixel 303 are arranged. The first pixel 301 includes no columnar spacer corresponding to a first columnar spacer 202b or a second columnar spacer 202c; the second pixel 302 has no contact hole formed in a second interlayer insulation film 8b under the first columnar spacer 202b; the third pixel 303 includes no common wiring line; and the third pixel 303 has no contact hole formed in a third interlayer insulation film 8c under the second columnar spacer 202c.SELECTED DRAWING: Figure 2 【課題】複数種類の高さを有する柱スペーサと同様の柱スペーサを形成可能な技術を提供することを目的とする。【解決手段】液晶表示装置は、第１画素３０１、第２画素３０２及び第３画素３０３が配設された第１絶縁性基板及び第２絶縁性基板を備える。第１画素３０１には、第１柱スペーサ２０２ｂまたは第２柱スペーサ２０２ｃに相当する柱スペーサが備えられず、第２画素３０２の第１柱スペーサ２０２ｂ下の第２層間絶縁膜８ｂにはコンタクトホールが設けらず、第３画素３０３には共通配線が備えられず、第３画素３０３の第２柱スペーサ２０２ｃ下の第３層間絶縁膜８ｃにはコンタクトホールが設けられない。【選択図】図２
