| 摘要 |
The invention provides a holder frame, optical device and projector which can prevent the substrate from deviating in position, the substrate from being compressed at the outer periphery and color unevenness from occurring. More particularly, in the four sides of a luminous-flux incident surface of a holder frame, there can be formed a plurality of cutouts extending from a vicinity of an opening to an outer edge of the luminous-flux incident surface and nearly orthogonal to a lengthwise of each side. Also, in the four sides of an accommodating surface of the holder frame, there are formed a plurality of cutouts extending from a vicinity of an opening to an outer edge of the accommodating surface and nearly orthogonal to a lengthwise of each side. The cutouts in each side of the accommodating surface of the holder frame are formed in positions between the cutouts formed in each side of the luminous-flux incident surface of the holder frame as viewed from a side of luminance-flux incidence.
