Abstract:
1. A display apparatus, comprising: a substrate; and a plurality of light emitting elements arrayed on said substrate and each formed from a lower electrode, a light emitting function layer and an upper electrode stacked in this order on said substrate; wherein a rib for element isolation is provided on said substrate and has a plurality of openings individually corresponding to said light emitting elements, and each of said openings of said rib is formed such that at least one of sides which define a shape of the opening in plan is formed only from a curved line having a waveform or from a straight line which extends in a non-parallel relationship to a side of another one of said openings, wherein each of the openings of the rib are formed so as to have a trapezoidal shape in plan wherein at least one of sides of the opening extends in a non-parallel relationship to an opposite side of the opening, and wherein the trapezoidal shapes are alternately disposed in a direction of the rib such that, for adjacent openings, narrow portions defining tops of the trapezoidal shapes and wide portions defining bottoms of the trapezoidal shapes are reversed.
