OPTICAL DEVICE AND IMAGE DISPLAY APPARATUS

摘要

An optical device includes a glass plate, a movable section that supports the glass plate, shaft sections that swingably support the movable section around a swing axis, a support section that supports the shaft sections, a permanent magnet provided in the movable section, a coil that is so disposed as to face the permanent magnet and produces a magnetic field acting on the permanent magnet, and a coil support section that is supported by the support section and supports the coil, and the coil support section is made of a material having thermal conductivity higher than that of the support section and intersects the in-plane direction of a light incident surface.

1. An optical device comprising:
an optical section having a light incident surface on which light is incident; a movable section that supports the optical section; a shaft section that swingably supports the movable section around a swing axis; a support section that supports the shaft section; a permanent magnet provided in the movable section; a coil that produces a magnetic field acting on the permanent magnet; and a coil support section that supports the coil, wherein the coil support section is made of a material having thermal conductivity higher than thermal conductivity of the support section and intersects an in-plane direction of the light incident surface.
