Title:
液晶表示装置
Document Type and Number:
Japanese Patent JP4407690
Kind Code:
B2
Abstract:
A semi-transmission liquid crystal display device of an in-plane switching mode includes M scanning signal lines, N video signal lines, switching elements, and a unit display area. The unit display area includes a first pixel electrode and a first counter electrode, a first storage capacitor, a second pixel electrode and a second counter electrode, and a second storage capacitor. A first voltage V1 is applied to the first counter electrode. A second voltage V2 is applied to the second counter electrode. When a higher one of the voltages V1 and V2 is represented as Hi (V1,V2) and a lower one of the voltages V1 and V2 is represented as Low (V1,V2), a third voltage equal to or lower than Hi (V1,V2) and equal to or higher than Low (V1,V2) is applied to the first pixel electrode and the second pixel electrode on the basis of an operation of the switching elements.
