Abstract

A display is provided. The display includes 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 the display relative to a region in which the light emitting section is disposed and regions in which the display cell and the light receiving cell are formed, wherein a phase difference plate is disposed at a position which is on the front side relative to the light receiving cell and in either of an emitting optical path of the light emitting section and a reflecting optical path toward the light receiving cell.

Description

[0001] Cross References to Related Applications [0002] The present invention contains subject matter related to Japanese Patent Application JP 2007-326176 filed in the Japan Patent Office on December 18, 2007, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to a display provided with a light emitting element in a display pixel portion or on an architrave-like frame thereof. Background technique [0004] Several technologies of a display device itself provided with a coordinate input function have been proposed. [0005] Specifically, for example, a display device of a pressure-sensitive type touch panel system (see Japanese Patent Laid-Open Nos. 2002-149085 and 2002-41244), a display device of an electromagnetic induction type touch panel system (see Japanese Patent Laid-Open No. Hei 11) are known. -134105) etc. [0006] However, a display device provided with such a coordinate input function as desc...
