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.
