An object of the present invention is to provide a liquid crystal display having a high luminance and a high contrast and a fabrication method thereof. In a simple manufacturing process, insulating layers are formed by anodizing on a portion of a thermally conductive board body and plated with a conductive material. The pivot arm is pivotally mounted to the table assembly, and includes a driver and a dust collection passage. Accordingly, an oscillation frequency corresponding to the first state and corresponding to the second state alternately appear, and therefore, it is possible to find the period of the vibration. The resistive layer comprises metallic or semiconducting nanoparticles or aggregates thereof in which the nanoparticles or aggregates thereof are separated by insulating andor semiconducting material. The load cell outputs a drive signal to drive the auxiliary wheels.
