<P>PROBLEM TO BE SOLVED: To provide a light-emitting device capable of suppressing increase in the number of mask sheets and increase in the number of steps, and of enhancing chromatic purity of light emission from a light-emitting element with a simple configuration, in a light-emitting device utilizing resonance effect of light between a pair of electrodes. <P>SOLUTION: A light-emitting device has first to third light-emitting elements each including a reflection electrode layer, a light-emitting layer, and a semi-transmissive electrode layer. In the first light-emitting element, the light-emitting layer is formed to contact with the reflection electrode layer, and the semi-transmissive electrode layer is formed to contact with the light-emitting layer. In the second light-emitting element, a first transparent electrode layer is formed to contact with the reflection electrode layer, the light-emitting layer is formed to contact with the first transparent electrode layer, and the semi-transmissive electrode layer is formed to contact with the light-emitting layer. In the third light-emitting element, a second transparent electrode layer is formed to contact with the reflection electrode layer, the light-emitting layer is formed to contact with the second transparent electrode layer, and the semi-transmissive electrode layer is formed to contact with the light-emitting layer. A film thickness of the first transparent electrode layer is different from that of the second transparent electrode layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
