摘要： The display apparatus including a microelectromechanical (MEMS) shutter is disclosed. The MEMS shutter is shifted by the switching element in a horizontal direction corresponding to the light control area to turn on or turn off the light control area. A first slit transmits light generated from the light source to the MEMS shutter of a first substrate and a second slit of a second substrate corresponding to the first slit provides apertures by overlapping the first slit and the second slit. The apertures of the MEMS shutter are distributed on a two dimensional plane and form a geometrically symmetric pattern that are capable of enhancing light-use efficiency.

摘要： A light guide unit includes a light guide plate and a plurality of light-exiting protrusions. The light guide plate includes a light-entering surface, an upper surface connected to the light-entering surface and a lower surface facing the upper surface. The light-exiting protrusions protrude from the upper surface of the light guide plate to have a cylindrical shape in which a cross-section size thereof increases in a direction away from the upper surface of the light guide plate, the light-exiting protrusions being disposed in a light control area which is turned on or off by a microelectromechanical system shutter. Light guided by the light guide unit to the light control area exits through the light-exiting protrusions.

摘要： A light-emitting chip includes a light-emitting part, a first color-converting part and a second color-converting part. The light-emitting part includes a first electrode and a second electrode, and generates first light of a first wavelength. The first color-converting part is formed on a light-emitting surface of the light-emitting part. The first color-converting part converts at least a portion of the first light into second light of a second wavelength. The second color-converting part is formed on the first color-converting part. The second color-converting part converts at least a portion of the first light into third light of a third wavelength that is shorter than the second wavelength. Thus, a fluorescent substance of a long wavelength and a fluorescent substance of a short wavelength are sequentially formed on a light-emitting surface of a light-emitting part, so that the color reproducibility of a light-emitting chip may be enhanced.
