Patent number: 10032837Abstract: An organic electroluminescent display device for improving light extraction efficiency is provided. A bank has an opening part at a position of a light-emitting surface of OLED. A sealing film is formed along an inside surface of the opening part, which is formed by a bottom surface where the light-emitting surface exists and a sidewall part of the bank rising from the bottom. A light-transmitting film is laminated on the sealing film and covers the opening part. The sidewall part of the bank includes a first sidewall part and a second sidewall part which is higher than the first sidewall part in height from the substrate. An inclination of the second sidewall part is greater than that of the first sidewall part, and a refractive index of the light-transmitting film is smaller than a refractive index of the sealing film in contact with the light-transmitting film.Type: GrantFiled: August 23, 2017Date of Patent: July 24, 2018Assignee: Japan Display Inc.Inventor: Chunche Ma
