US 2017/0373128 A1 · DISPLAY APPARATUS

Abstract

A display apparatus includes a substrate, a display unit over the substrate, the display unit including a thin film transistor, a display element connected to the thin film transistor, and a planarization layer between the thin film transistor and the display element. The display unit includes a display area to display an image, and a non-display area outside of the display area. The non-display area includes a plurality of voltage lines. The planarization layer extends into the non-display area and includes a divisional portion that divides the planarization layer into a central portion and a peripheral portion. The divisional portion surrounds the display area. An interlayer insulating film is between voltage lines at intersections of the voltage lines with each other in the divisional portion. A protecting film covers a side of the interlayer insulating film in the divisional portion.
