Abstract
Disclosed is a light guide member comprising a light-transmitting sheet (2) having a first surface (21) and a second surface (22) with a thickness of 200-800 μm, a light-transmitting photocurable resin layer (4) attached to the first surface (21), and a light-transmitting photocurable resin layer (6) attached to the second surface (22). The photocurable resin layer (4) has a mat structure in the surface, while the photocurable resin layer (6) has a prism array structure in the surface. The total of the average thickness of the photocurable resin layer (4) and the average thickness of the photocurable resin layer (6) is not more than 30μm.
