Patent ID: 7808164

Claim:
A display device comprising: a first light-transmitting substrate; a second light-transmitting substrate; a transistor over the first light-transmitting substrate; a light emitting element including a first electrode and a second electrode with a light emitting layer interposed therebetween, wherein the light emitting element is interposed between the first light-transmitting substrate and the second light-transmitting substrate, wherein the light emitting element emits light to both a first light-transmitting substrate side and a second light-transmitting substrate side, and wherein the first electrode is electrically connected to the transistor; at least first and second stacked linear polarizing plates, wherein the first light-transmitting substrate is interposed between the light emitting element and the at least first and second stacked linear polarizing plates; and at least third and fourth stacked linear polarizing plates, wherein the second light-transmitting substrate is interposed between the light emitting element and the at least third and fourth stacked linear polarizing plates, wherein the first and second stacked linear polarizing plates are provided directly in contact with each other through an adhesion surface of the second stacked linear polarizing plate, and wherein the third and fourth stacked linear polarizing plates are provided directly in contact with each other through an adhesion surface of the fourth stacked linear polarizing plate.
