A sign apparatus includes a sign cabinet with a window (4) inclined towards the observation plane. Inside the window, which is a color filter, there is arranged a panel (5) with electrically driven character elements (7). The angle of inclination ( beta ) of the panel is equal to, or less than, the angle of inclination ( alpha ) of the window. Each character element is formed by obliquely disposed rows of light emitting diodes.
