Display apparatus

Abstract

A display apparatus comprises a substrate including a display pixel area, 110A, a dummy pixel area, 110B, and a non-display area, 110C. A plurality of pixels, P, are disposed in the display pixel area and are electrically connected to a gate line, SL1, SL2, ELC1, ELC2, a data line, DL, a pixel driving power line, (PL, Figure 2) and an initialization voltage line, IVL. A plurality of dummy pixels, DP1, disposed in the dummy pixel area are electrically connected to a dummy gate line, SL1’, SL2’, ECL1’, ECL2’, the data line, DL , the pixel driving power line, and a dummy initialization voltage line, IVL’. An initialization voltage supply line is disposed in the non-display area and is electrically connected to the initialization voltage line disposed in the display pixel area and to the dummy initialization voltage line. The arrangement is designed to prevent luminance deviation and improve image quality. [Figure 6]
