To provide an organic EL display device capable of preventing erroneous light emission with which display luminance in black level is pushed up to that in gray level. [Means for Solving the Problem]In the first invention, the current drive circuit having output pins common for the first and second organic EL panels is provided. Therefore, there is no need of providing current drive circuits for the respective first and second organic EL panels.

摘要： In a conventional optical waveguide using a photonic crystal, loss of light occurs in the substrate therebelow. The invention provides an optical waveguide comprising a substrate, a core portion formed on the substrate, and clad portions arranged on the substrate so that the core portion is sandwiched therebetween. The clad portions each have a periodic structure which exhibits a periodic variation in refractive index in a direction perpendicular to a light propagation direction, and at least one of the periodic structures is inclined with respect to a surface of the substrate so that an interval between the periodic structures is gradually reduced toward the substrate. The slim, compact optical waveguide can be fabricated in a relatively simple and easy process, incurs lower loss, offers satisfactory light propagation characteristics, and has adequate mechanical strength.
