    • A display apparatus, includes: a substrate; a plural light emitting elements provided on the substrate and each formed from a lower electrode, a light emitting function layer and an upper layer stacked in this order; a partition for element isolation provided on the substrate and having a plural apertures individually corresponding to the light emitting elements; and a black matrix disposed on the light extraction side of the light emitting elements and having a shape with which the black matrix covers over portions. Each of the apertures of the partition having a side wall is formed in such a tapering shape that the aperture width increases toward the light extraction side of the light emitting elements. The black matrix is provided in such a manner as to cover over an upper edge portion of the tapering shape on at least one side which defines each aperture of the partition.
