Abstract
Without housing a bare chip type liquid crystal driver within a package, to surely shield or absorb the light which reaches the liquid crystal driver so that erroneous display due to the photoelectric effect can be prevented. A light shielding tape is affixed to the top surface of an upper panel of a liquid crystal display panel at an area which is opposite to the mounting area of a liquid crystal driver mounted on the bottom surface of the upper panel . The light shielding tape serves to shield the outer light incident on the liquid crystal driver . A diffusion sheet composed of a light diffusing area and a light absorbing area located on the outer periphery thereof is arranged below the liquid display panel . The light diffusing area serves to diffuse illumination light from a light source to the liquid crystal display panel , and the light absorbing area serves to absorb the extraneous light incident on the liquid crystal driver
