An active-matrix display device includes: a pixel matrix that includes a plurality of pixel cells arranged in rows and columns; a first global power supply wire that is disposed for each of the columns in the pixel matrix and connected to each of the plurality of pixel cells in the column; and a second global power supply wire that is disposed for each of the columns in the pixel matrix and connected to each of the plurality of pixel cells in the column. Each of the plurality of pixel cells includes a local power supply wire that is connected to the first global power supply wire, and the local power supply wire does not overlap the second global power supply wire in a plan view of the pixel matrix.
