Abstract:
1. A light emitting device comprising: a pixel portion having a plurality of EL elements each of which comprises a first electrode, an organic compound layer on and in direct contact with the first electrode, and a second electrode on and in direct contact with the organic compound layer between a pair of substrates at least one of which has a light transmitting property; a first sealing agent having first, second, and third patterns, the first and second patterns extending parallel along respective nearby two sides of the third pattern and sandwiching the pixel portion therebetween, and, wherein the first, second, and third patterns are not in contact with each other, thereby openings being formed between the third pattern and ends of the first and second patterns near corners of the third pattern; and a second sealing agent provided in a first region which is surrounded by the first and second patterns and another two sides of the third pattern so as to cover an entire surface of the pixel portion and partially protruding from the first region to at least a second region which is surrounded by one of the first and second patterns and the nearby side of the third pattern via one of the openings; wherein the pair of substrates is fixed with the first sealing agent and the second sealing agent, wherein the first sealing agent comprises an UV curable epoxy resin and includes a gap material maintaining a gap between the pair of substrate, and wherein the second sealing agent comprises a heat curable epoxy resin and has a light transmitting property.
