Abstract
According to one embodiment, a display device includes a first substrate including a common electrode and a pixel electrode, a second substrate, a liquid crystal layer, a first alignment film and a second alignment film. The pixel electrode includes a plurality of branch portions extending in a first direction and a connection portion extending in a second direction, wherein the first alignment film and the second alignment film are photo-alignment films, and the first alignment film has an anchoring strength of 1*10−3J/m2 or less.

A display device comprising:
- a first substrate including a common electrode disposed over a plurality of pixels, and a pixel electrode disposed in each of the pixels and opposed to the common electrode;
- a second substrate opposed to the first substrate;
- a liquid crystal layer disposed between the first substrate and the second substrate;
- a first alignment film provided on the first substrate and being in contact with the liquid crystal layer;
- and
- a second alignment film provided on the second substrate and being in contact with the liquid crystal layer, wherein
- the pixel electrode includes:
- a plurality of branch portions extending in a first direction;
- and
- a connection portion extending in a second direction intersecting the first direction and connected to the branch portions,
- the first alignment film and the second alignment film are photo-alignment films, and
- the first alignment film has an anchoring strength of 1*10−3J/m2 or less.
A method for manufacturing a display device, the display device comprising:
- a first substrate including a plurality of pixel electrodes and a common electrode opposed to the pixel electrodes;
- a second substrate opposed to the first substrate;
- a liquid crystal layer disposed between the first substrate and the second substrate;
- a first alignment film provided on the first substrate and being in contact with the liquid crystal layer;
- and
- a second alignment film provided on the second substrate and being in contact with the liquid crystal layer, wherein
- each of the pixel electrodes includes:
- a plurality of branch portions extending in a first direction;
- and
- a connection portion extending in a second direction intersecting the first direction and connected to the branch portions,
- the first alignment film and the second alignment film are photo-alignment films formed by photo-alignment treatment with UV-rays, and
- a total exposure value of UV-rays for forming the first alignment film is different from a total exposure value of UV-rays for forming the second alignment film.
