Abstract: A liquid crystal display device includes a first substrate having a plurality of first electrodes, a second substrate facing the first substrate and having a plurality of second electrodes perpendicular to the first electrodes to define sub-pixels at intersection regions between the first and second electrodes, a liquid crystal layer between the first and second substrates, a plurality of color filters between the first and second substrates adapted to correspond to respective sub-pixels, the color filters including first color filters and second color filters having a different shape than the first color filters, a black matrix between the color filters, the black matrix including vertical portions, horizontal portions, and step portions, each of the step portions corresponding to a respective second color filter, and a plurality of patterned spacers between the first and second substrates, each of the patterned spacers overlaps with a respective step-portion of the black matrix.

Abstract: A spindle motor, having a hydrodynamic pressure bearing, including: a stator including a core, on which at least one winding coil is wound, and a base provided with a central hole formed through the central area of the main body thereof so that the core is placed on the upper surface thereof; a rotor including a hub having a magnet formed on the outer circumference thereof to correspond to the winding coil leaving a designated interval with the winding coil, and a stop ring installed on the inner circumference of the hub; and a sleeve, for supporting the rotation of the rotor, including at least one dynamic pressure generating groove formed on the outer surface thereof correspondingly contacting the inner circumference of the hub and the stop ring, and a hub receiving hole formed through the central area of the main body thereof assembled with the central hole of the base.
