Abstract: In an organic EL display device, a taper angle of a separation layer surrounding edges of an organic EL layer disposed in each pixel and being disposed between adjacent pixels is different from a taper angle of a frame-shaped bank surrounding edges of an organic layer. As a result, qualities required for layers surrounded by the separation layer and the frame-shaped bank respectively are satisfied.

Abstract: A first protruding portion that has a surface having liquid-philic properties to an ink material and has a frame shape and a second protruding portion that has a surface having liquid-repellent properties to the ink material, surrounds the first protruding portion such that at least a part of the first protruding portion is located inside, and has a frame shape are formed so as to surround an electro-optical element. Then, the ink material is applied to a region surrounded by the first protruding portion and is cured, and thus an organic layer that seals the electro-optical element is formed.

Abstract: A method of manufacturing a display device includes a step of forming a first inorganic film constituting a sealing film and a step of forming an organic film constituting the sealing film. Between these steps, the method further includes a foreign matter inspection step of inspecting a substrate surface on which the first inorganic film has been formed and identifying the location of a foreign matter adhering to the substrate surface, and a partial ejection step of using an ink-jet method to eject ink to be formed a part of the organic film at the location of the foreign matter on the substrate surface identified in the foreign matter inspection step.

Abstract: An organic EL display device includes: a first support member having flexibility; an organic EL layer layered in a matrix form on the first support member; and a second support member disposed opposite the first support member with the organic EL layer interposed between the first support member and the second support member. Grooves on the first support member and grooves on the second support member overlap with one another. As a result, flexibility of the organic EL display device can be enhanced.

Abstract: An organic EL display device including pixels each including an organic EL layer formed, the pixels disposed in a matrix shape in a display region, includes a frame-shaped bank surrounding a periphery of the display region and including dot-shaped banks forming a plurality of columns and disposed in a staggered manner. Thus, a decrease in quality is prevented by preventing an irregular shape of an edge of a liquid material applied entirely to a surface of the display region to seal the organic EL layer.
