Abstract: There is provided a camera module including: a lens; an image pickup device arranged on an optical axis of the lens; and an actuator section configured to reciprocate the image pickup device in an optical axis direction of the lens, wherein the actuator section includes a movable joint section on which the image pickup device is fixed, a parallel link mechanism section having a movable end section attached to the movable joint section and a mounting end section, and a movable element that is configured to perform displacement motion by a displacement amount depending on a level of a voltage to be applied and that is coupled to a coupling region between the movable joint section and the movable end section of the parallel link mechanism section in such a manner that the displacement motion is transmittable.

Abstract: The present invention provides an antireflection substance such as an antireflection film having a low moisture-permeable characteristic, high quality and high reliability, and also provides a display apparatus comprising this antireflection substance. The antireflection substance according to the present invention includes an antireflection film formed on a transparent substrate, the antireflection film being composed of a multiple layer in which a first layer serving as an adhesion-improving layer, a second layer serving as a barrier layer against moisture, a third layer, a fourth layer and a fifth layer are laminated in this order, and in which the second layer and the fourth layer are each set to have a refractive index higher than that of the third layer and the fifth layer. The display apparatus according to the present invention comprises this antireflection substance on its display surface.
