The display device uses a diode to control an associated primary color output transistor so that a specific color is intensely reproduced. A diode is associated with each of three primary color output transistors which provide an output for switching in accordance with received bands of television signals. These associated switches are provided between the electronic tuner and the power source for the circuitry. The diode associated with each primary color output transistor is on-off controlled by a pulse so a predetermined pulse width is generated following the termination of a period responsive to the magnitude of the tuning voltage which starts from the time at which the horizontal blanking pulse is generated. Because of the generation of the controlling pulse at the horizontal synchronization, a vertically extending bar or stripe is reproduced in the specified color in accordance with the reception band.
