<p><P>PROBLEM TO BE SOLVED: To provide an organic EL lighting device which has a high uniformity ratio. <P>SOLUTION: An organic EL lighting device includes at least a first electrode 2, an organic layer 4, and a second electrode 3. The organic layer 4 is held by an anode part 2a of the first electrode 2 and a cathode part 3a of the second electrode 3. The second electrode 3 has an electron application part 3c which is narrower than the cathode part 3a. A width W4 of the electron application part 3c is less than half the width W1 of a hole application part 2c of the first electrode 2. A low resistance wiring part 7 is formed on an anode wiring part 2b of the first electrode 2. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
