    Abstract: At the rear of liquid crystal display elements 11R 11G, an 11B, each for displaying one component of a primary color, a red EL light source 10R, a green EL light source 10G and a blue EL light source 10B for emitting red color light, green color light, and blue color light are disposed, respectively. Each EL light source includes an organic EL element in which an organic thin film emits light. Each EL light source has a structure in which an organic luminescent layer 14 is sandwiched between an ITO electrode 13 and a metal electrode 15 which have striped patterns which are orthogonal to each other, and sections (luminescent sections) at which the striped patterns of the ITO electrode 13 and the metal electrode 15 intersect with each other emit light. The luminescent sections are arrayed two-dimensionally on a glass substrate 12 and illuminate the entire display area of the liquid crystal display element.

    Abstract: PROBLEM TO BE SOLVED: To extend the service life of a light source by restraining the brightness drop of an organic EL element of a display device using the element as the light source. SOLUTION: A red EL light source 10R, a green EL light source 10G and a blue EL light source 10B respectively emitting red color, green color and blue color are arranged behind the rear sides of liquid crystal display elements 11R, 11G and 11B respectively for displaying one color component of primary color. Respective light sources are formed out of an organic EL element having an organic thin film capable of emitting light. Also, each EL light source has a structure where organic luminous layers 14 are clamped with an ITO electrode 13 and a metal electrode 15 having stripe type patters orthogonal with each other. In this case, light is emitted from a part (light emission part) where the stripe type patterns of the ITO electrode 13 and the metal electrode 15 are orthogonal with one another.
