Abstract

A blue phase liquid crystal display device and a method for driving the same are disclosed. In the display device, there is a pixel electrode or a common electrode arranged right opposite to each of the viewing angle switching electrodes. In a narrow viewing angle mode, a vertical electric field can be generated between two electrodes that are arranged right opposite to each other, so that liquid crystal molecules in the vertical electric field can be in a vertical alignment state. According to the present disclosure, since almost all oblique light can pass through the liquid crystal molecules in the vertical alignment state, the probability that the viewing angle switching dead area occurs can be reduced to a large extent.
