摘要： A filling material is provided in an interval part between a first substrate provided with a light emitting device in a pixel and a second substrate provided with a color filter layer corresponding to each pixel which is provided to face each other and a protruding part is provided in the interval part. The protruding part is provided separated along one edge of each pixel. An end part in a length direction of the protruding part is formed in a cone or streamlined shape. In addition, the protruding part is formed from a material having light absorbing properties such as carbon black so as to provide light shielding properties. By adopting this structure, it is possible to solve a problem of mixing colors produced between pixels. It is possible to ensure that the flow of the filling material provided between the first substrate and the second substrate is not obstructed.

摘要： A display device includes a plurality of emitting elements corresponding to a plurality of pixels. The emitting element includes a lower electrode, an upper electrode having a light-transmitting property, and a light-emitting layer between the lower electrode and the upper electrode. The lower electrode includes a flat portion and an inclined portion that is inclined obliquely upward and outward from the central area of the flat portion. Both of the flat portion and the inclined portion include a reflective surface respectively. The reflective surface of the flat portion has a light reflectance lower than that of the reflective surface of the inclined portion.
