To provide a liquid crystal display device in which leakage of light caused by an alignment error is prevented, degradation in performance characteristics of a thin film transistor accompanying formation of an unnecessary thin film caused by a stepped portion of a light blocking member is prevented, and a thin film transistor is easily repaired.SOLUTION: A liquid crystal display device includes: a first insulation substrate; a gate line 121 disposed on the first insulation substrate; a first data line 171 and a second data line 171 each disposed on the first insulation substrate; a color filter that is disposed on the first insulation substrate and disposed between the first data line and the second data line; a first light blocking member 220 disposed on the first data line and the second data line; and a second light blocking member 330 disposed on the color filter and the first light blocking member, extending in the same direction as the gate line, and overlapping the first light blocking member on the first data line and the second data line.SELECTED DRAWING: Figure 2 【課題】整列誤差による光漏れを防ぎ、遮光部材の段差に起因する不要な薄膜形成に伴う薄膜トランジスタの性能特性の低下を防ぐとともに、薄膜トランジスタを修理しやすい液晶表示装置を提供する。【解決手段】第１の絶縁基板と、前記第１の絶縁基板の上に配設されているゲート線１２１と、前記第１の絶縁基板の上に配設されている第１のデータ線１７１及び第２のデータ線１７１と、前記第１の絶縁基板の上に配設されており、前記第１のデータ線と前記第２のデータ線との間に配設されているカラーフィルタと、前記第１のデータ線と前記第２のデータ線の上に配設されている第１の遮光部材２２０と、前記カラーフィルタと前記第１の遮光部材の上に配設され、前記ゲート線と同じ方向に伸び、前記第１のデータ線と前記第２のデータ線の上において前記第１の遮光部材と重なり合う第２の遮光部材３３０と、を備える液晶表示装置。【選択図】図２
