Abstract:
1. A display apparatus comprising: a plurality of light emitting devices and a plurality of device control circuits for controlling current passing through said light emitting devices, said light emitting devices and said device control circuits being arranged on a substrate in a row direction and column direction to form a display area, wherein each of said light emitting devices has a lower first electrode and an upper second electrode on the substrate, the first electrode being provided for each light emitting device and electrically connected to an associated device control circuit for said light emitting device, and the second electrode being an electrode common to all said light emitting devices and extending to a periphery of the display area; a first interconnecting line, disposed along a side of the display area, for supplying electric power to said device control circuits through power lines disposed in the display area; a second interconnecting line disposed along a side of the display area to have an overlapping area overlapping with the extending second electrode through an insulating layer disposed therebetween, said second interconnecting line being electrically connected to the extended second electrode in a contact hole provided in the insulating layer in the overlapping area; and an external connection terminal disposed at a peripheral portion of said apparatus along any one of the sides of the display area and electrically connected to said first interconnecting line and said second interconnecting line, wherein at the peripheral portion of said apparatus side along one of the sides of the display area at which said external connection terminal is disposed, said first interconnecting line is disposed outside said second interconnecting line with respect to the display area, and said first interconnecting line and said second interconnecting line establish a crossing with an overpass and underpass at an end portion of the peripheral portion, said first interconnecting line being disposed inside said second interconnecting line with respect to the display area at a side of the display area where the power lines are electrically connected to said first interconnecting line.
