Summary:PROBLEM TO BE SOLVED: To provide a pixel circuit capable of reducing display variation among pixels and providing high display quality.SOLUTION: A display device is provided which includes a pixel region having a plurality of pixels and a drive circuit located outside the pixel region. The pixels include: a drive transistor and switching transistor each having a gate and a pair of terminals; a light-emitting element having an input terminal; and a holding capacitor having a pair of terminals. One terminal of the switching transistor is electrically connected with the gate of the drive transistor and one terminal of the holding capacitor. One terminal of the drive transistor is electrically connected with the other terminal of the holding capacitor and the input terminal. The drive circuit includes a first transistor and a second transistor each having a gate and a pair of terminals. The other terminal of the switching transistor is connected with one terminal of the first transistor and one terminal of the second transistor. The second transistor has a channel region including an oxide semiconductor.SELECTED DRAWING: Figure 5 【課題】画素間での表示ばらつきが軽減され、高い表示品質を提供できる画素回路を提供する。【解決手段】複数の画素を有する画素領域と、画素領域外に位置する駆動回路を有する表示装置が提供される。画素は、それぞれゲートと一対の端子を有する駆動トランジスタとスイッチングトランジスタ、入力端子を有する発光素子と、一対の端子を有する保持容量を有する。スイッチングトランジスタの一方の端子は、駆動トランジスタのゲートと保持容量の一方の端子と電気的に接続される。駆動トランジスタの一方の端子は、保持容量の他方の端子と入力端子と電気的に接続される。駆動回路は、それぞれゲートと一対の端子を有する第１のトランジスタと第２のトランジスタを有する。スイッチングトランジスタの他方の端子は、第１のトランジスタの一方の端子と第２のトランジスタの一方の端子と接続される。第２のトランジスタは、酸化物半導体を含むチャネル領域を有する。【選択図】図５
