Abstract
An indicator comprises a liquid crystal display panel for internally housing patterns to be displayed, and a plurality of switches which are operated in unison with a light path switching mechanism for controlling the operation of the liquid crystal display panel. When an objective path of an optical instrument is connected with either one of a viewfinder path, a photometric path, a photographing path or the like by the action of a light path switching mechanism, the liquid crystal display panel indicates the particular light path with which the objective path is connected.
