Abstract
An image reading device in which light receiving elements formed on a first substrate are disposed in opposition to light emitting elements formed on a second substrate with a transparent layer being interposed therebetween. The transparent layer is made of a material whose reflectivity is smaller than that of the second substrate. In another embodiment, gas layers are provided between the transparent layer and the light emitting elements and the gas therein has an index of refraction less than the second substrate. Light transmitting windows provided in an opaque electrode of the light emitting elements have peripheral portions where no light is emitted.
