Abstract
An organic electroluminescent device includes first and second electrode and an organic light emitting layer. The first electrode has an upper face. The organic light emitting layer is provided on the first electrode. The second electrode is provided on the organic light emitting layer. The second electrode includes a plurality of conductive parts. The conductive parts extend in a first direction parallel to the upper face and are arranged in a second direction. The second direction is parallel to the upper face and intersects with the first direction. When a length of each of the conductive parts in the second direction is set to W1 (micrometer), and a pitch of each of the conductive parts is set to P1 (micrometer). The W1 and the P1 satisfy a relationship of W1≧−647(1−W1/P1)+511 and a relationship of W1≦−882(1−W1/P1)+847.
