PURPOSE:To reduce the number of manufacturing processes and to facilitate the manufacture by providing a colored condenser lens for respectively condensing light beams from the respective image elements of red, green and blue colors on a light emitting surface. CONSTITUTION:The colored condenser lens 16 is made to be bonded on the light emitting surface of a light emitting element 10 where respective red, green and blue image elements 11-13 are formed with a transparent adhesive layer 17. It is good for the condenser lens 16 to be uniformly colored so that the lens 16 may have the characteristic of a transmittivity uniform to a transmitted light beam, or it is good for the condenser lens 16 to be uniformly colored so that the red, green and blue light beams may be selectively transmitted, furthermore, even if the condenser lens 16 is respectively colored with other colors at every place corresponding to respective image elements 11-13 so that respective colored light beams emitted from respective image elements 11-13 may be selectively transmitted, the contrast between the state of all light emission and the state of non light emission increases, and by coloring the condenser lens 16 and making the lens have a filter characteristic, the number of the manufacturing processes can be reduced and also the manufacture can be facilitated. |
