Title: LIQUID CRYSTAL DISPLAY DEVICE
Abstract:
Provided is a horizontal orientation mode liquid crystal display that can achieve a high definition, and that can improve transmittance. This liquid crystal display device comprises a first substrate, a liquid crystal layer and a second substrate in that order, wherein the first substrate has a first electrode, a second electrode provided further towards the liquid crystal layer side than the first electrode, and an insulating film between the first electrode and the second electrode. The second electrode has an opening formed therein, and when a voltage is not applied, the liquid crystal molecules are oriented parallel with the first substrate, and in parallel with the initial orientation direction of the liquid crystal molecules, and if the outline of the opening is fragmented into four by a first straight line which fragments the opening to achieve a maximum length and a second straight line that is orthogonal to the direction of initial orientation, and that fragments the opening to achieve a maximum length, the average sign of the inclination of each of the fragmented outline parts is different to the average sign of the inclination of each of the two adjoining outline parts, and the average inclination of the overall outline of the opening is not zero.
