Zusammenfassung:	To provide a liquid crystal display device improving a black visual appreciation and an external appearance in a dark drive state.SOLUTION: A liquid crystal display device includes: a liquid crystal panel; a visible side polarizing plate laminated on a light emission face of the liquid crystal panel; and a first optical sheet and a second optical sheet sequentially laminated on a light incident surface of the liquid crystal panel. The visible side polarizing plate includes a polarizer and a light-dark ratio or view angle improvement layer. The liquid crystal panel includes a horizontal direction being a long side and a vertical direction being a short side. The first optical sheet includes a plurality of first optical patterns on the light emission face. An angle formed by a lengthwise direction of the first optical pattern to the vertical direction is -10 degrees through +10 degrees.SELECTED DRAWING: Figure 1 【課題】暗い駆動状態でブラック視感及び外観を改善した液晶表示装置を提供する。【解決手段】液晶パネル、前記液晶パネルの光出射面に積層された視認側偏光板、及び前記液晶パネルの光入射面に順次積層された第１光学シート及び第２光学シートを備えており、前記視認側偏光板は、偏光子、及び明暗比又は視野角改善層を含み、前記液晶パネルは、長辺である水平方向及び短辺である垂直方向で構成され、前記第１光学シートは、光出射面に複数個の第１光学パターンを備えており、前記垂直方向に対して前記第１光学パターンの長さ方向がなす角度は－１０゜乃至＋１０゜である液晶表示装置を構成する。【選択図】図１
