<P>PROBLEM TO BE SOLVED: To provide a light emission device that suppresses display irregularity, reduces fluctuation in transistor characteristics in different pixels, or suppresses decrease in luminance accompanying degradation of a light emission element. <P>SOLUTION: The light emission device has pixels 120 having transistors 121 provided on a substrate 100, and light emission elements 109. The transistor includes a single crystal semiconductor layer 122 where a channel forming region is formed, and has a silicon oxide layer provided between the substrate and the single crystal semiconductor layer. A source or a drain of the transistor is electrically connected to an electrode of the light emission element, and the transistor operates in a saturation region when the light emission element emits light. The grayscale display of the light emission element is carried out by changing a potential applied to the gate of the transistor. <P>COPYRIGHT: (C)2013,JPO&INPIT |
