Abstract: An LCD device comprises: a light irradiating portion; a microlens array having a plurality of microlenses for collecting light emitted from the light irradiating portion; and a liquid crystal panel having a plurality of unit pixels, each unit pixel matching with the plural microlenses, for displaying an image by passing light that has been collected into the microlens array through each unit pixel. According to this, a color degradation is reduced, a viewing angle is increased, a fabrication cost is reduced, and fabrication time is shortened.

Abstract: Disclosed is a liquid crystal display (LCD) device comprising: a liquid crystal panel having a black matrix of a grid type; and a trans-reflecting sheet positioned between a backlight source and the liquid crystal panel, for irradiating light generated from the backlight source and reflecting a certain ratio of external light introduced through the liquid crystal panel. The trans-reflecting sheet is fabricated by a micro-machining technique and a semiconductor fabricating process thereby to increase a brightness and a contrast of a liquid crystal screen. According to this, a visibility of an image is increased, a massive fabrication is possible, and a uniform degree between fabricated products is enhanced.

Abstract: An oil supply device of a scroll compressor includes a pumping unit mounted at a lower side of a rotating shaft and pumping oil stored at a lower portion of a casing according to rotation of the rotating shaft; an oil supply passage formed in a longitudinal direction of the rotating shaft and supplying oil pumped by the pumping unit to each friction portion; an oil channel formed at an upper surface of the main frame and connecting an oil groove formed at the upper surface of the main frame and a pocket formed at the center of the main frame; and an oil guide recess formed to connect the oil groove and the key hole formed at the main frame and guiding oil introduced into the oil groove to the key hole. By supplying oil to the key hole, abrasion between an oldhamring key and the key hold is prevented and noise is reduced, enhancing reliability of the compressor.
