A Liquid Crystal Display (LCD) device includes: a first substrate; a conductive layer arranged on one surface of the first substrate; an insulating layer arranged on the conductive layer and having a thickness of 3 &#x3bc;m or more; first electrodes arranged on the insulating layer and spaced apart from each other by an interval of 3 &#x3bc;m or less; a second substrate including a second electrode arranged on one surface to face the first substrate; and a liquid crystal layer interposed between the first and second substrates.

LCD device and method having first and second alignment layers arranged on respective first and second electrodes each layer having pretilt angles ranging between 5 to 20 degrees

A video signal copying apparatus for copying a signal recorded on a recording medium onto other recording media is provided. The video signal copying apparatus includes a first filter for blocking a color signal and passing a luminance signal of a video signal detected from a video signal recording medium, a second filter for passing only the color signal of the video signal, a burst detection signal generator for generating a burst detection signal for detecting a burst signal, a color signal determiner for generating a color killer signal when a color signal does not exist in the video signal, a peak level detector for detecting the peak level of the input signal over all frequency bands when the color killer signal is generated, or over only a burst detection signal section when the color killer signal is not generated, by receiving the filtered color signal, a voltage-controlled amplifier for automatically controlling the gain of the color signal in correspondence to the detected peak level, and a mixer for mixing the filtered luminance signal and the gain-controlled color signal to output a video signal to be recorded via a recording amplifier. Therefore, loss of a luminance signal which is part of a low-frequency component can be prevented when copying a black and white signal, thereby improving picture quality.

Video signal copying apparatus

A dual-deck VCR includes a delaying portion for delaying a color signal of 629 KHz reproduced from one deck by a horizontal scanning period, a color comb filter for removing crosstalk from the delayed color signal and a not-delayed color signal, a burst level processing portion for integrating the burst to output the integrated level of the burst and a color gain controller for controlling the amplitude of the color signal output from the color comb filter in response to the integrated level output from the burst level processing portion. The characteristics of the components of the dual-deck VCR are chosen so that crosstalk and a pickup noise generated from the non-uniformity of friction between head and tape are removed.
