PROBLEM TO BE SOLVED: To decrease illuminance unevenness near a corner part of a display screen in a liquid crystal display device employing an in-plane switching system and having a curved display screen.SOLUTION: A liquid crystal display device employing an in-plane switching system and having a curved display screen is provided, which includes: a first substrate bent in a first direction and including a plurality of gate lines, a plurality of date lines, pixel electrodes and a common electrode; a second substrate bent in the first direction, disposed to oppose to the first substrate and including a polarizing plate; a liquid crystal layer disposed between the first substrate and the second substrate; a sealing material for bonding the first substrate with the second substrate; and a driver for outputting a drive signal to at least either the plurality of gate lines or the plurality of data lines. The polarizing plate, in at least a part of a side thereof close to the driver, overlaps the sealing material or is located outside the sealing material in a plan view.SELECTED DRAWING: Figure 1 【課題】曲面状の表示面を有する横電界方式の液晶表示装置において、表示画面のコーナー部付近に生じる輝度ムラを低減する。【解決手段】液晶表示装置は、曲面状の表示面を有する横電界方式の液晶表示装置であって、第１方向に曲げられ、複数のゲート線と複数のデータ線と画素電極と共通電極とを含む第１基板と、前記第１方向に曲げられ、前記第１基板に対向配置され、偏光板を含む第２基板と、前記第１基板及び前記第２基板の間に配置される液晶層と、前記第１基板及び前記第２基板を貼り合わせるためのシール材と、前記複数のゲート線及び前記複数のデータ線の少なくとも何れか一方に駆動用信号を出力する駆動ドライバと、を含み、平面的に見て、前記偏光板は、少なくとも前記駆動ドライバに近い辺の一部が、前記シール材に重なっている、又は、前記シール材より外側に位置している。【選択図】図１
