DISPLAY APPARATUS AND ELECTRONIC DEVICE
First Claim
1. A display apparatus, comprising:
- a substrate;
a plurality of light emitting elements provided over said substrate and each formed from a lower electrode, a light emitting function layer and an upper layer stacked;
a partition for element isolation provided over said substrate and having a plurality of apertures corresponding to said light emitting elements; and
a light shielding portion disposed on the light extraction side of said light emitting elements and having a shape with which said black matrix covers over portions between said light emitting elements;
whereineach of said apertures of said partition having a side wall is formed in such a tapering shape that the aperture width increases toward the light extraction side of said light emitting elements,wherein the light shielding portion is provided to cover at least upper edge portions of the tapering shape on a first side of the aperture for at least a first one of the light emitting elements and a second side of the aperture for at least a second one of the light emitting elements, the first side being different than the second side.

Abstract
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.
