A PC board consisting of a conductive layer laid through an insulating layer on a metal plate surface is easily bendable to make any desirable shape. This permits any desired distance to be provided between the display element and the PC board. In addition, it is possible to form display element- fixing angles integrally with the PC board. As a result, the number of components required is decreased and production efficiency improved. Moreover, the metal plate of the PC board protects the display device from unnecessary radiation. external noises and/or static electricity.
