Abstract
There is provided a liquid crystal display wherein a first display region corresponding to a first area on which first pixel electrodes are provided displays an image by light reflection mode, and a second display region corresponding to a second area on which second pixel electrodes are provided can display an image by light transmission mode.
Claims24
A liquid crystal display, comprising:
- first and second substrates facing each other;
- first pixel electrodes arrayed on at least one continuous first area within a surface of the first substrate facing the second substrate;
- second pixel electrodes arrayed on at least one continuous second area within the surface of the first substrate facing the second substrate, the second area being spaced apart from the first area;
- a first common electrode supported by the second substrate and facing first pixel electrodes;
- a second common electrode supported by the second substrate and facing the second pixel electrodes;
- and
- a liquid crystal layer interposed between the first pixel electrodes and the first common electrode and between the second pixel electrodes and the second common electrode, wherein a first display region corresponding to the first area displays an image by light reflection mode, and a second display region corresponding to the second area can display an image by light transmission mode.
