To provide a display apparatus which is intended to improve the miniaturization and illumination efficiency, an indicatoris disposed on the rear surface side of a transparent display panel. A printed boardmounts a movementon the front surface thereof so as not to overlap the movementand the transparent display paneland mounts the indicatoron the rear surface thereof. LEDsfor the transparent display panel are mounted on the front surface of the printed boardso as to oppose to the outer peripheral surface of the transparent display panel

Display apparatus

A steering column cover body accommodates therein at least one of an electric junction block, a meter and at least one switch which are directly connected with each other. The switch includes at least one of a turn switch, a wiper switch, a hazard switch and an ignition switch. The meter includes a circuit board on which a first circuit for driving the meter and a second circuit for driving the at least one switch is mounted.

A figure defining system (39, 43, 46, 57) defines a first figure as a pointer (43) on a background plate (39) and a second figure as a character plate (46) with characters and divisions, a figure illuminating system (39a, 43a, 47, 49, 55a, 51, 53) includes a rear light transmitting plate (47) for illuminating the pointer (43) as a figure element of the first figure to be visible, the rear light transmitting plate extending along a first plane, a top light transmitting plate (49) for illuminating the characters and divisions as figure elements of the second figure to be visible, the second light transmitting plate extending along a second plane crossing the first plane, and a common light source (51) disposed in a corner chamber partially defined by an end face of the rear light transmitting plate and an end face of the top light transmitting plate, and a half mirror (41) arranged between the first and second planes for displaying a combination of an optical image of the first figure, as it is transmitted through the half mirror, and an optical image of the second figure, as it is reflected on the half mirror, to have images of the figure elements combined to be visible in a display field.
