Patent ID: 8500302

Claim:
A display panel apparatus, comprising: a substrate; organic electroluminescence units, each of which includes a first electrode above said substrate, a second electrode that is a transparent electrode, and an organic luminescent layer between said first electrode and said second electrode; a lens sheet including a sheet base and lenses, said sheet base being outside said second electrode in a first direction of light emitted from said organic luminescent layer, said lenses being respectively provided for said organic electroluminescence units and protruding from a first surface of said sheet base; a transparent substrate above said lens sheet; and a bonding layer across a top surface of said lens sheet and including a resin for providing a flat surface over an unevenness resulting from said lenses and for bonding said lenses and said transparent substrate, wherein one of said substrate and said organic electroluminescence units has an alignment mark for aligning said substrate with said lens sheet, said lens sheet has a groove between said lenses in said sheet base and recessed from the first surface of said sheet base in a second direction opposite to a third direction in which said lenses protrude, and said groove between said lenses is for alignment with said alignment mark, the resin covers a second surface of each of said lenses and is in said groove, and a boundary area between said sheet base and each lens of said lenses is covered by the resin, the boundary area being located between the second surface of said lens and said groove.
