Classification: CPC H  G | IPC G  H

Claim 0:
1. A display device comprising:
a pixel including:
a first electrode;
a second electrode; and
a light-emitting layer between the first and second electrodes;

a bank covering a part of the first electrode;
a hole transport layer; and
a functional layer, wherein
the bank has an opening including a first opening and a second opening extending from the first opening in such a direction that the second opening overlaps the first electrode,
the second opening at least partially overlaps the first electrode,
the first electrode has an end located close to the first opening and overlapping either the second opening or a periphery of the first opening,
the second opening has a maximum width smaller than a maximum width of the first opening, the maximum widths of the first and second openings being measured perpendicular to a direction in which the second opening extends from the first opening,
the first electrode is an anode,
the hole transport layer is between the anode and the light-emitting layer, and
the functional layer includes at least the light-emitting layer in the first opening and the second opening, and has a larger thickness in the second opening than in the first opening.
