Organic EL display device

An organic EL display device, comprising:

• a plurality of organic EL elements each including:
• an organic light emitting layer configured to emit white light;
• an upper electrode that is formed on an upper side of the organic light emitting layer over which an image is displayed;
• and
• a reflective layer that is formed on a lower side of the organic light emitting layer;
• a first substrate on which the plurality of organic EL elements are formed;
• a second substrate that seals the plurality of organic EL elements on the first substrate;
• and
• a color filter on the second substrate,
• wherein
• the reflective layer in each of the organic EL elements includes:
• a first plane;
• a second plane that is formed on a side lower than the first plane;
• and
• an inclined plane that is formed between the first plane and the second plane, and linearly inclined at a given angle equal to or higher than 35°, and equal to or lower than 55°,
• the reflective layer includes a plurality of concave portions formed to be depressed on the basis of the first plane,
• respective side walls of the plurality of concave portions are configured by the inclined plane, and
• respective bottoms of the plurality of concave portions are configured by the second plane.
