Abstract

To provide an aspect of a novel display device using a light emitting element which is composed of a cathode, an EL layer and an anode, and a manufacturing device of the display device. According to the present invention, dual-sided emission display can be performed in one sheet white color light emitting panelin which, for example, different images can be displayed on a topside screen and backside screen (full color display, monochrome display or area color display). Two polarizing platesare formed by shifting the position thereof with an angular deviation of 90 degrees each other so as to prevent outside light from passing through the pane, thereby realizing a black display when not displayed.
