Abstract: PROBLEM TO BE SOLVED: To make inconspicuous the sticking border s of a display having screens constituted in divisions and to make sticking margins wide. SOLUTION: A display panel 30 has pixels P32, adjacent to a joined surface 36, formed having smaller display areas than other pixels P20 and P30. Consequently, the width W30 of the margin of the display panel 20 is wider than the width W20 of the joined surface 36. Consequently, sticking operation can be performed with a margin. The margin of the joined surface 36 is made wide and then an organic electric field light emitting element is excellently sealed from external air and element deterioration is reducible. The luminance of the pixels P32 is compensated by a method of amplifying and applying a driving signal etc.
