A lens member 3, which is disposed behind an LED display part 2 formed as a small rectangular hole in a front wall of a cabinet 1 of a display device, includes a plate-like substrate part 3a, a light receiving part 3b formed on a back surface of the substrate part like a spherical recess, and a light condensing part 3e formed integrally on a front surface of the substrate part 3a so as to be opposed to the light receiving part 3b, having a tip engaging the LED display part 2. The light condensing part 3e rises from the front surface of the substrate part 3a with inclination having a rectangular section at a lower end covering the light receiving part 3b.
