Abstract
An end (that is, an end (130b)) of a second electrode (130) of a k-th light-emitting unit (152(k)) on a second side (S2) exists on the outer side of an end (152b) of the k-th light-emitting unit (152(k)) by the width WR(k) of an overlapping region (OR). In one example, the width WR(k) is equal to or greater than d×tan(arcsin(sin θl(k)/ns)) and equal to or less than 3d×tan(arcsin(sin θl(k)/ns)) (d×tan(arcsin(sin θl(k)/ns))≤WR(k)≤3d×tan(arcsin(sin θl(k)/ns))).
