    摘要: A light guide plate according to one embodiment of the present invention includes two glass sheets and a scattering layer sandwiched between and integrated with the glass sheets, wherein the scattering layer is a transparent resin film formed by stretching, and wherein the light guide plate has a haze of 0.2% or higher as determined according to JIS K 7136. The light guide plate is suitable for use in an edge-light-type surface light emitting apparatus. It is preferable that the scattering layer is a biaxially stretched transparent polyethylene terephthalate film. It is also preferable that the light guide plate further includes an adhesive resin layer between the scattering layer and the glass sheet.
