Patent ID: 8175451

Claim:
An electronic viewfinder apparatus which is provided in an imaging apparatus, comprising: a reflective type liquid crystal display that outputs an optical image signal; a finder optical system that collects the optical image signal outputted from the reflective type liquid crystal display; and a transmission plate that transmits a part of the optical image signal collected by the finder optical system therethrough and reflects at least a part of the remaining optical image signal, wherein the reflective type liquid crystal display includes: a light source that emits light; a liquid crystal plate disposed on an optical axis of the finder optical system such that a surface of the liquid crystal plate thereof is perpendicular to the optical axis; a reflecting plate that is disposed on a back side of the liquid crystal plate and on the optical axis of the finder optical system such that a reflection plane of the reflecting plate is perpendicular to the optical axis, and that reflects light emitted from the light source through the liquid crystal plate; and a polarizing plate that is disposed to be inclined so as not to be perpendicular to the optical axis of the finder optical system, the polarizing plate reflecting light emitted from the light source toward a side of the reflecting plate and allows the light passing through the liquid crystal plate and reflected by the reflecting plate to pass therethrough toward a side of the finder optical system as an optical image signal, and the transmission plate is disposed to be inclined in a direction opposite to an inclined direction of the polarizing plate such that a transmission plane thereof is not perpendicular to the optical axis of the finder optical system.
