Abstract:
1. A current drive type display apparatus, comprising: a display area in which are disposed on a substrate a plurality of current drive type light emitting devices and a plurality of pixel circuits that control a drive current for the current drive type light emitting devices; and a peripheral area, on the substrate, in which are disposed first and second interconnecting lines that supply current to the pixel circuits; wherein each of the current drive type light emitting devices includes a first electrode as a lower layer, a second electrode as an upper layer, and a plurality of layers of an organic compound disposed between the first and second electrodes, wherein each pixel circuit is connected to the first interconnecting line and supplies the drive current to an associated current drive type light emitting device through the first electrode, wherein the second electrode is connected, through a contact hole provided in said peripheral area, to the second interconnecting line which is in a layer of said apparatus that is lower than the second electrode, wherein at least said display area and the contact hole are covered with a passivation layer; and wherein at least along one side of the substrate in said peripheral area, the second interconnecting line is disposed immediately under the contact hole and the first interconnecting line is disposed between the second interconnecting line and one edge of the substrate and between the second interconnecting line and said display area.
