Electroluminescent display

An EL display comprising,

• a panel board including a display screen on which pixels each including an EL element are arranged in a matrix;
• gate signal lines arranged on a per pixel row basis;
• source signal lines arranged on a per pixel column basis;
• gate driver circuits mounted on a flexible board;
• and
• a source driver circuit which outputs a video signal to the source signal lines,
• wherein each of the gate driver circuits includes gate signal output terminals, first driver terminals, second driver terminals, and control terminals,
• first connection parts, gate signal connection parts, second connection parts, and third connection parts are arranged on the flexible board, and
• the flexible board includes (i) terminal connection lines which connect the gate signal output terminals and the gate signal connection parts, (ii) terminal connection lines which connect the control terminals and the second connection parts, and (iii) serial connection lines which connect the first connection parts, the driver terminals, and the third connection parts.
