  • Publication number: 20190019969
    Abstract: In the display device according to the present disclosure, three segments have the same total areas which are sum of the area of the lower electrode and the area of the cover wiring, and response speeds of the three segments are the same when the drive current is supplied. Since there is no difference in response speeds to the drive current between the segments, even if luminance adjustment is performed by a pulse width modulation, the luminance difference between the segments does not occur.

  • Publication number: 20180212004
    Abstract: A display device capable of suppressing rapid degradation of a lifespan. The display device (1) includes a light emitting region 2 and a non-light emitting region 3 formed above a substrate (11). The display device (1) includes: a first electrode (13) provided above the substrate (11); a second insulating film (14) that includes an opening (14a) exposing the first electrode (13) of the light emitting region (2) and is formed in the non-light emitting region (3) above the substrate (11); an organic EL layer (15) provided above the first electrode (13) via the opening (14a); and a second electrode (16) provided above the second insulating film (14) and the organic EL layer (15). A plurality of holes (16a) dotted throughout the non-light emitting region (3) are formed in the second electrode (16).

  • Patent number: 9905621
    Abstract: An organic electro-luminescence display device includes: a first substrate having transmissive properties; a touch electrode for a touch sensor, the touch electrode being provided on a main surface of the first substrate; an insulating film provided on the main surface and covering the touch electrode wherein the insulating film includes a first surface at the touch electrode-side and a second surface opposite to the first surface; an organic light-emitting element provided on the second surface of the insulating film; a second substrate provided facing the main surface of the first substrate; and an integrated circuit electrically connected with both the touch electrode and the organic light-emitting element. The touch electrode, the insulating film, and the organic light-emitting element are interposed between the first substrate and the second substrate.
