  • Patent number: 10444902
    Abstract: A touch sensor includes first electrodes which are driving electrodes of the touch sensor, second electrodes which are detecting electrodes of the touch sensor, third electrodes, and an insulating film which is stacked on the first electrodes. Each of the first electrodes extends in a first direction. Each of the second electrodes and each of the third electrodes are formed on the insulating film, and extend in a second direction. The second electrodes overlap with partial regions of the first electrodes, and the third electrodes overlap with other partial regions of the first electrodes and are formed in gaps between the second electrodes. A film thickness of the insulating film between the first electrodes and the third electrodes varies due to pressing force in a film thickness direction, and the insulating film constitutes the electrostatic capacitance-type pressure sensor with first electrodes and the third electrodes.

  • Patent number: 10032837
    Abstract: 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.
