PROBLEM TO BE SOLVED: To provide a light-emitting transistor including an organic semiconductor material and having an improved light-emitting efficiency, and to provide a light-emitting device including the same.SOLUTION: An organic light-emitting transistor further having an additional electrode between a gate insulating layer and an organic semiconductor layer, has an improved light-emitting efficiency. With respect to the conductivity of the additional electrode, when a sheet resistance is 10 k&OHgr;/sq. or less, the light-emitting efficiency is further improved. Since a light-emitting device includes the organic light-emitting transistor further having the additional electrode, the light-emitting efficiency is improved. |
