Abstract
Reflective display and transmissive display are performed by driving liquid crystal in a predetermined area (region b) in a non-crossing region by using an oblique electric field. Light passed through the region b when a voltage is applied is shaded since the liquid crystal in the region b is driven. Accordingly, at a position of a second substratecorresponding to the region b, it is not necessary to provide a shading filmConsequently, a line width Sof the shading filmcan be designed to be smaller compared to that of a conventional one, and hence, a high aperture ratio can be obtained.
