In an IPS type liquid crystal display device, it is attempted to improve display quality. In the IPS type liquid crystal display device, in the case where a liquid crystal layer is of a positive liquid crystal, a counter electrode is divided for each display line. When two adjacent display lines are defined as one display line and the other display line, respectively, a gap between the counter electrode of the one display line and the counter electrode of the other display line extends in a direction of the display line as a whole while bending locally. The gap has a first portion extending along an extending direction of a video line and a second portion extending from the first portion along a direction crossing the video line. An initial alignment axis of the liquid crystal layer is in a direction within a range of +5° to +20° or -5° to -20° clockwise with respect to the video line. When an angle measured clockwise from the initial alignment axis of the liquid crystal layer to the second portion of the gap is theta1, a relation of 88°<=theta1<=92° is satisfied. The video line is formed of a light-shielding material, and the first portion of the gap is planary overlapped with the video line.
