PROBLEM TO BE SOLVED: To provide a surface light emitter that produces uniform luminance when arranged at the back of a COG type liquid crystal module for the construction of a liquid crystal display. SOLUTION: An edge-light type surface light emitter is for use in a liquid crystal display that includes a COG type liquid crystal module comprising a glass substrate directly mounted with driving LSI chips 6. The surface light emitter comprises a transparent photoconductive plate, a line light source 8 on one side of the photoconductive plate, a light-diffusion transmission part on the back of the photoconductive plate, a back reflecting plate 10 on the back of the transmission part, a band-like photo-absorptive layer 11 formed in the peripheral region of the reflecting plate 10 on the side facing the photoconductive plate at least near to the line light source 8, and a diffusing sheet on the surface of the photoconductive plate. The photo-absorptive layer 11 is widened at its positions near to the LSI chips 6 corresponding to the arrangement pitch thereof. |
