Patent ID: 8786790

Claim:
A liquid crystal display device having a plurality of pixels, comprising: a lens array unit including a cylindrical lens array constituted by a plurality of cylindrical lenses each having a lens surface and a generatrix corresponding to the lens surface, the lens surface being arranged in a line in a direction orthogonally crossing the generatrix; a first substrate arranged at a back side of the lens array unit and including a pixel electrode in a belt shape extending in a different direction from the direction in which the generatrix extends, the pixel electrode being formed in a V character shape extending in first and second extending directions different from the generatrix in each pixel; a second substrate arranged between the lens array unit and the first substrate including a counter electrode in a belt shape commonly arranged above the pixel electrode and extending in a parallel direction to the pixel electrode, the counter electrode being formed in a V character shape extending in the first and second extending directions in each pixel; and a liquid crystal layer containing liquid crystal molecules and held between the first substrate and the second substrate; wherein the generatrix of the cylindrical lens at each position of the arrangement direction of the cylindrical lens crosses the pixel electrode and the counter electrode in the character V shape respectively extending in the first and second extending directions, and a line segment in which the generatrix crosses an aperture formed between the pixel electrode and the counter electrode is constant in each position, and wherein the generatrix at each position of the arrangement direction of the cylindrical lens crosses a bright region and a dark region, and a length of a line segment in which the generatrix crosses the bright region is approximately equal at each position of the arrangement direction of the cylindrical lens when the liquid crystal molecules are aligned in a state corresponding to a bright display.
