Abstract
Provided is an electronic view finder for use in a video camera apparatus that by making the relative position between an LCD and an ocular lens unit proper can decrease the rotatory polarization characteristic and can thereby enhance the contrast of the image. When a liquid crystal image screen surface has the characteristic of Viewing-Angle that this screen surface is seen with its contrast or brightness being different according to the direction in which to see the screen surface, the center of an eye-cup opening portion ( ) on the light emission side of an ocular lens unit ( ) is shifted from an optical axis ( ) of the ocular lens unit ( ). Thereby, an observer's eye is guided to a position detached from the position corresponding to the optical axis ( ) to see the liquid crystal image screen surface ( ) from an oblique direction. It has been thereby arranged to enable the liquid crystal image screen surface to be observed with an excellent contrast.
