| description | PROBLEM TO BE SOLVED: To provide an optical device that can be easily manufactured and radiates heat of an inorganic polarizing plate.SOLUTION: An optical device includes a first optical modulator modulating a first color beam, a second optical modulator modulating a second color beam, and a color synthesizing optical unit for synthesizing the color beams individually modulated by the first optical modulator and the second optical modulator. The optical device further includes an exit side polarizing plate 42M disposed at a light exit side of the first optical modulator, a transparent substrate 43 being laminated on the exit side polarizing plate 42M and transmitting light, a support part 7 supporting the first optical modulator and being attached to the color synthesizing optical unit, and a holding part 8 holding the exit side polarizing plate 42M and the transparent substrate 43 together with the support part 7. The holding part 8 has a bent part 85 engaging with the support part 7 and a biasing part 86 biasing the exit side polarizing plate 42M toward the transparent substrate 43 by engagement of the bent part 85 with the support part 7. The support part 7 has a reception part for receiving the transparent substrate 43 pressed by the biasing part 86.SELECTED DRAWING: Figure 9
【課題】製造が容易で、無機偏光板の熱を放熱する光学装置を提供する。【解決手段】第１色光を変調する第１光変調装置と、第２色光を変調する第２光変調装置と、第１光変調装置および第２光変調装置でそれぞれ変調された色光を合成する色合成光学装置と、を備えた光学装置であって、第１光変調装置の光射出側に配置された射出側偏光板４２Ｍと、射出側偏光板４２Ｍに積層され、光を透過する透明基板４３と、第１光変調装置を支持し、色合成光学装置に取り付けられる支持部７と、支持部７とで射出側偏光板４２Ｍと透明基板４３とを挟持する挟持部８と、を備える。挟持部８は、支持部７に係合する屈曲部８５と、屈曲部８５が支持部７に係合されることで、射出側偏光板４２Ｍを透明基板４３側に付勢する付勢部８６と、を有し、支持部７は、付勢部８６により押圧される透明基板４３を受ける受部を有している。【選択図】図９ |
