摘要： A display panel apparatus includes pixels. Each pixel includes an organic luminescent layer between an upper electrode and a lower electrode and is configured to emit a red, a green, or a blue light. A glass substrate is above the upper electrode. A lens sheet is between the pixels and the glass substrate and includes lenses and a base. Each lens corresponds to a pixel and protrudes from the base. Partitions are between the glass substrate and the lens sheet for partitioning the lenses. The partitions have a first height that is greater than a second height of the lenses. The base includes trenches between the lenses. The trenches are recessed in a direction opposite the lenses. The partitions are in the trenches. Each partition has a cross-section that includes an upper side that has a different length than a bottom side and lateral sides that are tilted.

摘要： An organic electroluminescence display includes a first electrode and an auxiliary wire each either on or in a substrate. A luminescent layer is over the first electrode, and a hole transport layer is between the luminescent layer and the first electrode. The hole transport layer extends from over the first electrode to over the auxiliary wire. A second electrode is over the luminescent layer and extends from over the first electrode to over the auxiliary wire. A metal layer is over the auxiliary wire between the hole transport layer and the second electrode. The second electrode and the auxiliary wire are electrically connected via the hole transport layer and the metal layer. The metal layer comprises a metal, wherein a difference of a work function value of the metal minus an absolute value of an energy level of a lowest unoccupied molecular orbit of the hole transport layer is at most approximately 0.5 eV.
