<p><P>PROBLEM TO BE SOLVED: To provide an edge light panel capable of enhancing a front face brightness, capable of reducing an uneven brightness, and capable of facilitating cutting work for a product model and manufacturing of a resin molding die for molding. <P>SOLUTION: This edge light panel 30 is formed of a translucent material and is formed into a sheet shape with a rectangular front face. A light from a fluorescence lamp incident into one end face (incident end face 31) is guided toward a deep end face faced to the incident end face 31. A plurality of irregular parts 40 is formed in a rear face (reflecting face 33). The irregular part 40 is provided with the first recessed part 41, and the second recessed part 42 formed in a deep end face side of the first recessed part 41. The first recessed part 41 is provided with the first sloped face 41a inclined in a shape with a deep side approaching the deep end face, on a cross section orthogonal to the incident end face and a radial face, and the second sloped face 41b inclined in a shape with a deep side approaching the incident end face 31, as wall faces, and the second recessed part 42 is provided with the third sloped face 42a inclined in a shape with a deep side approaching the deep end face, on the cross section, as a wall face. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
