Abstract:
1. An OCB mode liquid crystal display device comprising: a first substrate including a first insulating substrate, a first electrode located on the first insulating substrate, a second electrode located between the first insulating substrate and the first electrode via an insulating underlayer interposed between the second electrode and the first electrode, and a first alignment film on the first electrode; a second substrate including a second insulating substrate, a third electrode on the second insulating substrate, and a second alignment film on the third electrode; a liquid crystal layer which is held between the first electrode and the third electrode and which exhibits a transition from a first state to a second state in an initializing process; and a voltage supply unit which supplies, in the initializing process, a first voltage to the first and the second electrodes and a second voltage, which is different from the first voltage, to the third electrode, wherein the first electrode includes a transition nucleus forming section which forms at least one of nuclei of the transition in the liquid crystal layer on the basis of the respective voltages supplied to the respective electrodes, the transition nucleus forming section includes a bend pattern including a recess portion which is recessed more on an inside of the first electrode than an end side of the first electrode and a width of the recess portion in a direction of extension of the end side of the first electrode is ½ or more of a thickness of the liquid crystal layer, the first alignment film and the second alignment film are subjected to alignment treatment in mutually parallel directions, thereby defining an alignment direction in the liquid crystal layer, and a thickness of the insulating layer is ⅕ or more of a thickness of the liquid crystal layer.
