Abstract
A display apparatus including an electrically-controlled phase retardation layer, a reflective polarizer, a micro light emitting diode panel and a reflective layer is provided. The electrically-controlled phase retardation layer has a first side and a second side opposite to each other. The reflective polarizer is disposed at the first side of the electrically-controlled phase retardation layer. The micro light emitting diode panel is disposed at the second side of the electrically-controlled phase retardation layer and includes a circuit substrate and a plurality of micro light emitting diodes. The reflective layer is disposed between the reflective polarizer and the circuit substrate. An orthogonal projection of the reflective layer on the circuit substrate is not overlapped with orthogonal projections of the micro light emitting diodes on the circuit substrate.
