Abstract:
1. A blue phase liquid crystal display device, comprising: a first substrate having a first pixel region; a first gate line on the first substrate; first and second data lines on the first substrate and crossing the first gate line; a first thin film transistor (TFT) and a second TFT disposed in the first pixel region, the first TFT connected to the first gate line and the first data line, and the second TFT connected to the first gate line and the second data line; a first pixel electrode in the first pixel region and connected to the first TFT, and a second pixel electrode in the first pixel region and connected to the second TFT, the first pixel electrode alternately arranged with the second pixel electrode such that the first pixel electrode is positioned between the first data line and the second pixel electrode in a plane view, wherein an electric field, which is substantially parallel to a surface of the first substrate, is generated between the first and second pixel electrodes; a second substrate facing the first substrate; and a liquid crystal layer between the first and second substrates, the liquid crystal layer having an optical isotropic property without an electric field and a birefringence property with the electric field, wherein the first TFT and the second TFT are switched by a gate signal through the first gate line, and wherein a first signal from the first data line is applied into the first pixel electrode through the first TFT, and a second signal from the second data line is applied into the second pixel electrode through the second TFT.
