[0120] 〔Organic electroluminescence element〕
[0121] Figure 4 This is a cross-sectional view in the thickness direction of the organic electroluminescence element (hereinafter referred to as an organic EL element) according to the first embodiment, and a part of the cross-section is enlarged and shown.
[0122] The organic EL element 1 is composed of a light-transmitting substrate 2 , a light output layer 3 , a transparent electrode 4 , an organic light-emitting layer 5 , and a counter electrode 6 laminated in this order.
[0123] (light-transmitting substrate)
[0124] The translucent substrate 2 is a smooth plate-shaped member for supporting the light output layer 3 , the transparent electrode 4 , the organic light emitting layer 5 and the counter electrode 6 . The organic EL element 1 is a so-called bottom emission type element in which the light output direction of radiant light generated by the organic light-emitting layer 5 is toward the translucent substrate 2 side....
