In one embodiment, a liquid crystal display device includes a lens array unit having 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 is arranged in a line in a direction orthogonally crossing the generatrix. A first substrate is arranged at a back side of the lens array unit and includes a pixel electrode in a belt shape extending in a different direction from the direction in which the generatrix extends. The pixel electrode is formed in a V character shape. A second substrate is arranged between the lens array unit and the first substrate including a counter electrode in a belt shape commonly arranged on the pixel electrodes extending in a parallel direction to the pixel electrode.

In one embodiment, a liquid crystal display device comprises a pixel electrode including a first main electrode disposed between a first line and a second line and extending like a belt in a first extending direction. A first counter electrode includes a second main electrode extending like a belt in the first extending direction, a second counter electrode having a third main electrode extending like a belt in the first extending direction. The second and third main electrodes are disposed on both sides of the first main electrode, and an initial alignment direction of the liquid crystal molecules is parallel with a direction passing through an interstice between the first end side of the first main electrode and the second line, and through an interstice between the second end side of the first main electrode and the first line.

A three-dimensional display device includes a pair of substrates arranged opposing each other, a liquid crystal layer held between the pair of substrates, and a display region including a plurality of display pixels arranged in a matrix. A light control element is provided opposing the display region and is arranged periodically in a first direction. The light control element has substantially same characteristics in a second direction. The first direction crosses the second direction for giving a parallax in the first direction. Each pixel includes a plurality of sub-pixels arranged in the second direction, and a ratio of areas of respective sighted regions of the plurality of sub-pixels is constant in each display pixel.

In one embodiment, a nonplanar display devise includes an array substrate and a counter substrate formed of non-glass material. The array substrate includes a polishing stopper layer formed on a glass substrate. A ground layer is formed on a polishing layer. A switching element is arranged on the ground layer, and a pixel electrode is connected to the switching element. The nonplanar display device is manufactures as follows. First, the glass substrate is removed from the display cell. Then, the polishing stopper layer of the array substrate is removed. Finally, the nonplanar display device is manufactured by attaching an exposed ground layer of the array substrate and an insulating layer formed of the non-glass material in the display cell.

In one aspect, a liquid crystal display device includes a display region formed of a plural divided regions in a row direction. First and second driving circuits are arranged to face each other interposing the display region therebetween in the row direction. The first driving circuit is connected with odd scanning lines, and the second driving circuit is connected with the even scanning lines. A channel area of the TFT of the pixels connected to the odd scanning lines is the smallest in the divided region nearest to the first driving circuit and becomes larger gradually in the divided regions distant from the first driving circuit. A channel area of the TFT of the pixels connected to the even scanning lines is the smallest in the divided region nearest to the second driving circuit and becomes larger gradually in the divided regions with distant from the second driving circuit.
