Abstract
An active-matrix display device includes a pixel matrix having a plurality of pixel cells arranged in rows and columns, and a data line disposed for each of the columns in the pixel matrix and connected to each pixel cell in a column. Each pixel cell includes a holding capacitor, including a first electrode connected to a gate of the drive transistor, a lower electrode connected to a source of the drive transistor, and an upper electrode connected to the source of the drive transistor. At least one of the lower electrode and the upper electrode protrudes toward the data line from a facing region in a plan view of the pixel matrix, such that a protruded amount, which is an amount of protrusion toward the data line, is greater than or equal to 15% of a distance between the data line and the first electrode in the facing region.
