PROBLEM TO BE SOLVED: To supply uniform electric power to each EL (electroluminescence) element of an EL panel. SOLUTION: A drive current line which supplies power to an EL element includes a branch line provided in a display region and a trunk line 26, 28 (72, 74) having a larger cross-sectional area than that of the branch line 20, provided along two or more sides of a peripheral portion of a display region. By providing the trunk line to surround the display region, the percentage of the trunk line along the route of the drive power supply line from a power supply terminal to a pixel is increased. With this structure, a voltage drop of the drive power supply is reduced and uniform power supply to each EL element of the El panel is achieved. COPYRIGHT: (C)2007,JPO&INPIT
