Display and electronic apparatus

A display comprising:

• at least one display cell having a display circuit;
• at least one light receiving cell including a light receiving element;
• a back light operative to illuminate a display surface at a predetermined luminance;
• a first transparent substrate provided with said display cell and said light receiving element;
• a second transparent substrate disposed opposite to said first transparent substrate;
• a liquid crystal layer disposed between said first transparent substrate and said second transparent substrate;
• a first polarizing plate formed on a surface, opposed to said back light, of said first transparent substrate;
• and
• a second polarizing plate formed on the front side of said second transparent substrate,
• wherein a phase difference plate is disposed at a position on the front side relative to said light receiving cell and in either of an emitting optical path of said back light and a reflecting optical path toward said light receiving cell.

An electronic apparatus having a display,

• said display comprising:
• at least one display cell having a display circuit;
• at least one light receiving cell including a light receiving element;
• a light emitting section operative to radiate light to the side of a display surface;
• and
• a polarizing plate disposed on the front side in said display relative to a region in which said light emitting section is disposed and regions in which said display cell and said light receiving cell are formed,
• wherein a phase difference plate is disposed at a position which is on the front side relative to said light receiving cell and in either of an emitting optical path of said light emitting section and a reflecting optical path toward said light receiving cell.
