AbstractA liquid crystal panel which can operate at high speed is provided. The liquid crystal panel is constructed such that an electric field having a direction parallel to substrates is formed between pairs of electrodes with respect to a liquid crystal layer in which TN type liquid crystal is disposed. This electric field boosts a change from a state in which major axes of liquid crystal molecules orient in a direction vertical to the substrates to a state in which the major axes orient in the direction parallel to the substrates. Thereby, the change of the states of the liquid crystal molecules which has relied only on orientation restricting force in the past may be accelerated. Then, it allows the liquid crystal panel to respond quickly.
