PROBLEM TO BE SOLVED: To control deterioration of visibility due to reflection of a daylight in an electrode inside an element. SOLUTION: Each pixel of an EL display panel 1 is provided with an organic EL element L laminated in an order of a pixel electrode 3, a hole transport film 4, a luminous layer 5, and an opposite electrode 6. The pixel electrode 3 and the opposite electrode 6 are translucent. The opposite electrode 6 is a common electrode for all the pixels and the whole surface is covered with a film and is laminated with a retro-reflection material 7. The retro-reflection material 7 has a characteristic of retro-reflecting light incoming from a side of the luminous film 5. COPYRIGHT: (C)2007,JPO&INPIT
