PURPOSE:To reduce a ghost image generated by total reflected optical beam on the circumferential surface of a color filter by slanting the circumferential surface of the color filter according to an incidence surface for an incident beam. CONSTITUTION:A color filter 6 has a circumferential bevel cut at the same angle with an incident beam 10. Consequently, no total reflection phenomenon by the beam 10 is caused and a ghost image due to total reflection is eliminated. On the other hand, an increase in the quantity of transmitted light from an air side may cause ghost image generation, but a light shielding part 12 is formed on the circumferential bevel to prevent the generation of a ghost image from the air side. |
