Abstract

See full text

A metal housing includes a printed circuit board, a display panel with an LCD panel, and an FPC that connects the printed circuit board and the LCD panel. An EH power source and an EL power source on the printed circuit board are used to drive pixel electrodes on the LCD panel. A series LC circuit and capacitors are disposed on the printed circuit board, and one end of the series LC circuit is connected to the ground and the other end is connected to power source wiring via the capacitors. The impedance characteristics of the series LC circuit and the capacitors C4 and C5 are set such that the impedance is sufficiently small in a frequency band of predicted ground noise and large in other frequency bands.
