Title:
PLANE LIGHT EMITTING PLATE
Document Type and Number:
Japanese Patent JPH05142424
Kind Code:
A
Abstract:
PURPOSE:To improve the brightness of the plane light emitting plate of a side light system with a fluorescent tube to be used as the back light of an LCD. CONSTITUTION:A resin layer 2 consisting of a transparent polymer is applied on at least the end face on which light is made incident of a photoconductive plate 1 constituting the plane light emitting plate, by which the end face is smoothed. Since the end face of the photoconductive plate is easily smoothed, the light of the fluorescent tube 3 is efficiently made incident on the inside of the photoconductive plate 1. The back light system improved in conversion efficiency is thus easily obtd.
