Abstract
An optical sheet () includes a pinhole mask including a plurality of pinholes and a microlens array including a plurality of microlenses. Positions and sizes of the plurality of pinholes and the plurality of microlenses allow light emitted from the sub-pixels of all kinds to enter a specific pinhole and be diffracted by the specific pinhole, thereby allowing each thus-diffracted light outputted from the specific pinhole to enter a specific microlens.
