Abstract:

To provide a reflection type liquid crystal cell which suppresses a light leakage caused in an opening part between pixels.

A plurality of pixels provided with a reflection layer are arrayed, the opening part is disposed in the reflection layer of an adjacent gap area and translucency is provided in the liquid crystal cell 100. A light controlling means 19 for reducing the re-feedback of an outer light which is made incident from the display surface of the liquid crystal cell 100 and passes to the rear surface of the cell 100 through the opening part in a display surface direction is arranged at least at the position of the opening part in the rear surface of the liquid crystal cell 100. The black layer of the light controlling means 19 is arranged on the rear surface of the cell 100. Or a polarizing board is combined with a quarter wavelength board. A defective pixel to be a luminescent spot is made to be a translucent area by trimming and cutting the reflection layer and converted into the defective pixel being a black inconspicuous spot through the use of the black layer.
