摘要： PROBLEM TO BE SOLVED: To provide a projector device provided with a microlens which can improve a contrast ratio, and a spatial light modulator having a concave surface-shaped part. SOLUTION: A projector device has a plurality of microlenses 12 placed by facing a pixel array of a spatial light modulator, and each of the microlens 12 is arranged so that a direction which is long in a radial direction (for example, cD direction) of each microlens 12 may match a vibration direction 18 of a linearly polarized light which is incident on the microlenses 12. Thus, the position in which no or little depolarization of the microlens array of the spatial light modulator occurs matches the vibration direction 18 of the incident linearly polarized light. Depolarization is thereby reduced, and the contrast ratio can be improved. COPYRIGHT: (C)2006,JPO&NCIPI
