According to a flexible OLED device production method of the present disclosure, a multilayer stack (100) is provided, the multilayer stack including a base (10), a functional layer region (20) which includes a TFT layer and an OLED layer, a flexible film (30) provided between the base and the functional layer region and supporting the functional layer region, and a dielectric multilayer film mirror (36) provided between the flexible film and the functional layer region. The flexible film is irradiated with lift-off light (216) transmitted through the base, whereby the flexible film is delaminated from the base.

A display device comprises an organic EL substrate including an organic EL layer formed on a flexible substrate and a first main surface of the flexible substrate; a film covering a display region of the organic

EL substrate; and a terminal region arranged at an end portion of the organic EL substrate, and arranged adjacent to and apart from an end portion of the film. The end portion of the film may have a taper region. A thickness of the taper region increases with distance from the terminal region in a cross-sectional view. A width of the taper region may be 0.5 times or more and 1.5 times or less of the film thickness in a plan view.

An organic-EL display apparatus comprises: a substrate comprising a first electrode; an organic layer formed of organic materials so as to form a plurality of pixels arrayed in a matrix form, the organic material being vapor-deposited on the first electrode; and a second electrode formed on the organic layer. Each of the plurality of pixels comprises at least three sub-pixels having substantially rectangular shapes; a first sub-pixel and a second sub-pixel among the at least three sub-pixels are arranged in parallel with each other such that a long side of the first sub-pixel and a long side of the second sub-pixel are substantially parallel with each other; and a third sub-pixel among the at least three sub-pixels is formed such that a long side of the third sub-pixel is substantially parallel with a short side of the first sub-pixel and a short side of the second sub-pixel. In the first sub-pixel and the second sub-pixel, a variation in a thickness of the organic layer through a long-side direction is larger than a variation in the thickness of the organic layer through a short-side direction; and in the third sub-pixel, a variation in a thickness of the organic layer through a short-side direction is larger than a variation in the thickness of the organic layer through a long-side direction.

A flexible display supporting substrate of the present disclosure includes: a glass base (11); a plastic film (12) which has a surface (12s), the surface having a polish recess (12c), the plastic film being supported by the glass base (11); and an oxide layer (20) overlying a part of the surface (12s) of the plastic film (12) and covering at least part of the polish recess (12c).

The disclosure relates to a method and apparatus for preventing oxidation or contamination during a circuit printing operation. The circuit printing operation can be directed to OLED-type printing. In an exemplary embodiment, the printing process is conducted at a load-locked printer housing having one or more of chambers. Each chamber is partitioned from the other chambers by physical gates or fluidic curtains. A controller coordinates transportation of a substrate through the system and purges the system by timely opening appropriate gates. The controller may also control the printing operation by energizing the print-head at a time when the substrate is positioned substantially thereunder.

Disclosed is a coating device which draws a pattern of a functional liquid on a substrate. The coating device includes: a substrate holding unit which holds the substrate; a droplet discharging unit which discharges a droplet of the functional liquid on the substrate held by the substrate holding unit; a moving unit which relatively moves the substrate holding unit and the droplet discharging unit in a main scanning direction and a sub scanning direction on a base; a mass measuring unit including a cup which receives the droplet discharged by the droplet discharging unit and a mass measuring device which measures a mass of the functional liquid accumulated in the cup; and a liquid drain unit which drains the functional liquid accumulated in the cup.

An organic electroluminescent device includes a substrate, driving circuit layer, inorganic protective layer, organic flattening layer, organic electroluminescent element layer, and TFE structure. The TFE structure includes a first inorganic barrier layer, organic barrier layer, and second inorganic barrier layer. The organic flattening layer is formed in a region where the inorganic protective layer is formed, organic electroluminescent elements are located in a region where the organic flattening layer is formed, and an outer perimeter of the TFE structure crosses lead wires and is present between an outer perimeter of the organic flattening layer and an outer perimeter of the inorganic protective layer. In a region where the inorganic protective layer and the first inorganic barrier layer are in direct contact with each other on the lead wires, a tapering angle of a side surface of a cross-section of the first inorganic barrier layer is smaller than 90 degrees.
