PROBLEM TO BE SOLVED: To provide a display device allowing a thinner bezel.SOLUTION: The display device comprise: a light-emitting element; a drive transistor connected to the light-emitting element; a first switching element connected to the drive transistor and a main power line; a second switching element connected to the drive transistor and a reset power source line; a third switching element connected to the drive transistor and a signal line; a fourth switching element connected to the third switching element and an initialization power source line; and a capacitive element connected to the drive transistor and the third switching element. An ON signal with two horizontal periods is supplied to respective gate terminals of the second switching element, the third switching element, and the fourth switching element.SELECTED DRAWING: Figure 2 【課題】狭額縁化を実現可能な表示装置を提供すること。【解決手段】表示装置は、発光素子と、発光素子に接続された駆動トランジスタと、駆動トランジスタ及び主電源線に接続された第１スイッチング素子と、駆動トランジスタ及びリセット電源線に接続された第２スイッチング素子と、駆動トランジスタ及び信号線に接続された第３スイッチング素子と、第３スイッチング素子及び初期化電源線に接続された第４スイッチング素子と、駆動トランジスタ及び第３スイッチング素子に接続された容量素子と、を有し、第２スイッチング素子、第３スイッチング素子、及び第４スイッチング素子のそれぞれのゲート端子には２水平期間のオン信号が供給される。【選択図】図２
