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.
