PROBLEM TO BE SOLVED: To provide a high-speed response mode liquid crystal display device having improved contrast.SOLUTION: A liquid crystal display device according to one embodiment includes first and second substrates and a liquid crystal layer. The first substrate includes a plurality of scan lines, a plurality of signal lines, a first electrode, a second electrode, and a light shielding layer. One of the first and second electrodes is a pixel electrode and the other is a common electrode. The first electrode includes a plurality of branch areas extending in a first direction and an axial area extending in a second direction and connecting each branch area. A gap area extending in the first direction between adjacent branch areas exists. The light shielding layer includes a plurality of first parts superimposed on the branch areas or the gap area, extended in the first direction, and arranged in the second direction. The first parts are arranged in positions closer to the liquid crystal layer than the scan lines and the signal lines on the first substrate.SELECTED DRAWING: Figure 5 【課題】 コントラストを改善した高速応答モードの液晶表示装置を提供する。【解決手段】 一実施形態の液晶表示装置は、第１及び２基板、液晶層を備える。第１基板は、複数の走査線、複数の信号線、第１電極、第２電極、遮光層を備える。第１及び第２電極の一方は画素電極であり、他方は共通電極である。第１電極は、第１方向に延在する複数の枝領域、第２方向に延在するとともに各枝領域を接続する軸領域を含む。隣り合う枝領域の間において第１方向に延びる隙間領域がある。遮光層は、枝領域又は隙間領域と重畳し、第１方向に延びるとともに第２方向に並ぶ複数の第１部分を含む。第１部分は、第１基板において走査線および信号線よりも液晶層に近い位置に配置されている。【選択図】 図５
