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 panel 1001 in 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 plates 1002, 1003 are 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.

2. A light emitting device comprising a pixel portion, the pixel portion comprising:
-
a light emitting element comprising;
a first transparent electrode;
a second transparent electrode; and
a light emitting layer between the first and second transparent electrodes; and
a color filter, wherein light emission from the light emitting layer and passing through the first transparent electrode generates a full color display on a first surface of the light emitting device by the color filter, and wherein light emission passing through the second transparent electrode generates a monochrome display on a second surface of the light emitting device. - View Dependent Claims (3, 4, 5, 6, 7, 8)
