Abstract:
1. A liquid crystal display apparatus, comprising: a liquid crystal layer containing a plurality of liquid crystal molecules; a first alignment film arranged to be adjacent to said liquid crystal layer; a first alignment region provided in said first alignment film, for aligning said liquid crystal molecules; a second alignment region provided in said first alignment film and arranged to be adjacent to said first alignment region, for aligning said liquid crystal molecules; a first electrode arranged opposite to said liquid crystal layer with respect to said first alignment film; a plurality of first slit portions formed in said first electrode, opposed to a portion of said first alignment region adjacent to a boundary line between said first alignment region and said second alignment region, and extending in a direction away from said boundary line; a plurality of second slit portions formed in said first electrode, opposed to a portion of said second alignment region adjacent to said boundary line, and extending in a direction away from said boundary line; a second alignment film opposed to said first alignment film with said liquid crystal layer being interposed; a third alignment region provided in said second alignment film and opposed to said first alignment region; a fourth alignment region provided in said second alignment film and opposed to said second alignment region; and a second electrode arranged opposite to said liquid crystal layer with respect to said second alignment film, said first alignment region and said third alignment region being formed such that liquid crystal molecules located in a central portion between said first alignment region and said third alignment region among said liquid crystal molecules are aligned in a first director orientation when a voltage is applied across said first electrode and said second electrode, said second alignment region and said fourth alignment region being formed such that liquid crystal molecules located in a central portion between said second alignment region and said fourth alignment region among said liquid crystal molecules are aligned in a second director orientation greater in angle of orientation than said first director orientation when a voltage is applied across said first electrode and said second electrode, with a direction toward said boundary line among directions of extension of said first slit portions being defined as a first extension orientation and a direction away from said boundary line among directions of extension of said second slit portions being defined as a second extension orientation, a difference between the angle of orientation of said second extension orientation and the angle of orientation of said second director orientation being greater than a difference between the angle of orientation of said first extension orientation and the angle of orientation of said first director orientation.
