Disclosed are a channel equalizer and digital television receiver using the same. The equalizer comprises a channel estimator, a channel distortion compensator and noise canceller. The channel estimator estimates an impulse response of a transmission channel from a received signal. The channel distortion compensator transforms and processes the received signal and the estimated impulse response. The noise canceller predicts and eliminates amplified noise generated during equalization.

An apparatus and a method for applying a conductive paste, for forming electrodes, onto an electronic component, such as a micro chip device. The apparatus includes a first jig unit provided with paste holes, which are filled with the conductive paste; and a second jig unit being movable and provided with extruding pins, which are inserted into the paste holes of the first jig unit, for allowing the conductive paste to be applied onto the electronic component. The conductive paste is applied onto the electronic component, while the electronic component is loaded onto or unloaded from the first jig unit. The apparatus and the method allow the conductive paste for forming electrodes to be precisely applied onto the electronic component, easily adjust the amount of the applied conductive paste, prevent the spreading of the conductive paste or the incorrect application of the conductive paste, allow jig units, for applying the conductive paste onto the electronic component, to be used for a long time without replacement or washing, cause the reduction of the maintenance costs of the apparatus, and facilitate the formation of electrodes having various shapes on the electronic component.

Disclosed is an OCB mode LCD device. The OCB mode LCD device includes a liquid crystal cell interposed between substrates, which are rubbed in a predetermined direction, an upper phase delay film aligned above the liquid crystal cell, an upper circular polarizing plate aligned below the upper phase delay film, a lower phase delay film aligned symmetrically to the upper phase delay film, and a lower circular polarizing plate aligned symmetrically to the upper circular polarizing plate and including an optical axis perpendicular to that of the upper circular polarizing plate. The optical axis direction of the polarizing plate is the same as the rubbing direction of the liquid crystal cell, thereby compensating for the phase delay caused by the liquid crystal molecules having the bend structure and realizing the completely dark state while ensuring wide viewing angle characteristics.
