Abstract: A laser crystallizing apparatus includes a laser generator that generates an incident laser beam that includes a P polarization component and an S polarization component, an optical system that converts the incident laser beam to generate an emitted laser beam, and a stage on which is mounted a target substrate with a target thin film which is laser-crystallized by being irradiated by the emitted laser beam. The optical system includes at least one half wave plate (HWP) that shifts a polarization axis direction of the incident laser beam received from the laser generator, at least one mirror that fully reflects the laser beam, and at least one polarization beam splitter (PBS) which reflects a part of the laser beam and transmits the other part of the laser beam.

Abstract: A light field display apparatus includes a display panel and a micro lens array. The display panel includes a plurality of sub-pixels arranged in a matrix. The micro lens array is disposed on the display panel. The micro lens array includes a plurality of micro lenses. Each of the plurality of sub pixels emits light of a single color, of a set of primary colors. The arrangement of the micro lens array, relative to the display panel, causes the light of certain sub pixels, of the plurality of sub pixels to be emphasized. The micro lens array is arranged, relative to the display panel, so that sub pixels of each primary color are emphasized to a same extent.
