    摘要： A display device includes a light-emitting element layer including a plurality of light-emitting elements. The light-emitting element layer includes, for each of the plurality of light-emitting elements, a first electrode and a plurality of openings exposing the first electrode, and includes an edge cover covering an end portion of the first electrode, a plurality of light-emitting layers covering each of the plurality of openings, and a second electrode that is common to the plurality of light-emitting elements and covers the plurality of light-emitting layers. The second electrode includes a metal nanowire. Furthermore, the light-emitting element layer includes an auxiliary wiring line provided in a lattice pattern in a position overlapping the edge cover, and the auxiliary wiring line and the metal nanowire are electrically connected to each other.

    摘要： An object of the present invention is to enhance a display quality of a liquid crystal display panel by causing a contour of a display region not to be noticeable. A display region of a liquid crystal display panel (100) includes a normal display region (101a) and a boundary display region (101c), an image being displayed more darkly in the boundary display region (101c), which is in contact with a black light blocking part (101b), than in the normal display region (101a).

    摘要： A method of producing display panels of collectively producing a plurality of display panels each including a contour line of an outer shape, at least a section of which is curved includes a bonding process of forming a bonded substrate by bonding a pair of substrates including a plurality of thin film patterns formed on at least one substrate, a stacking process of stacking a plurality of bonded substrates and pinching and holding the plurality of stacked bonded substrates in a stacking direction using a jig, and a grinding process of collectively forming end surfaces of the plurality of display panels forming the curved contour line by collectively grinding the pair of substrates located outside the thin film pattern among stacked bonded substrates along the outer shape in a state in which the plurality of stacked bonded substrate are pinched by the jig.

    摘要： To prevent the display quality from being degraded as a result of (i) a boundary portion of an edge region of the display region being visibly in the shape of stairs and/or (ii) emitted light having an unintended color, a display panel includes a light-shielding section including, for each pixel (5) through which a curved boundary line (ideal line) extends, sub-pixel light-shielding sections (3a) each overlapping a corresponding one of a red sub-pixel (4R), a green sub-pixel (4G), and a blue sub-pixel (4B).
