Abstract

PROBLEM TO BE SOLVED: To decrease the number of parts, to improve assembly workability, to shorten production time and to enhance the dimensional accuracy of the single parts of light shielding buffer members by an arranging an integrally molded frame-shaped light shielding buffer member between a liquid crystal display panel and a back light. SOLUTION: The frame-shaped light shielding buffer member IBF is formed integrally in the step along its frame, i.e., the frame shape having its groove G by molding of plastic in such a manner that the shape fits to the step parts at the ends of lower and upper transparent glass substrates SUB1, SUB2 constituting the liquid crystal display panel PNL. The frame-shaped liquid shielding buffer member IBF made of the plastic is arranged on the overhanging part between the prism sheet PRS of the back light BL and a diffusion sheet SPS and the side wall of the lower case MCA so as to pressurize and hold the upper transparent glass substrate SUB2 o the liquid crystal display panel PNL.
