Abstract

A display device includes a first region including a first light emitting element including a first electrode, a second region including a second light emitting element including a second electrode, a pixel defining layer including a first sidewall defining a first opening corresponding to the first electrode and a second sidewall defining a second opening corresponding to the second electrode, a first spacer which protrudes from the pixel defining layer in the first region and includes a first edge closest to the first opening, and a second spacer which protrudes from the pixel defining layer in the second region and includes a second edge closest to the second opening. A distance between the first sidewall and the first edge, is smaller than a distance between the second sidewall and the second edge.

Dependent claims

An electronic device comprising:

a display device comprising:
an outer edge defining a corner of the display device;
a front surface display region having a corner facing the corner of the display device and a first light emitting element which includes a first pixel electrode;
a corner display region which extends bent from the corner of the front surface display region to the corner of the display device, the corner display region having a second light emitting element which includes a second pixel electrode;
a pixel defining layer in the front surface display region and in the corner display region, the pixel defining layer including:
a first sidewall defining a first opening of the pixel defining layer which corresponds to the first pixel electrode, and
a second sidewall defining a second opening of the pixel defining layer which corresponds to the second pixel electrode,
a first spacer which is in the front surface display region, protrudes from the pixel defining layer adjacent to the first opening and includes a first edge closest to the first opening;
and
a second spacer which is in the corner display region, protrudes from the pixel defining layer adjacent to the second opening, and includes a second edge closest to the second opening,
wherein among the front surface display region and the corner display region, a distance between the first sidewall of the pixel defining layer and the first edge of the first spacer in the front surface display region is smaller than a distance between the second sidewall of the pixel defining layer and the second edge of the second spacer in the corner display region.

An electronic device comprising:

a display device including:
an outer edge defining a corner of the display device;
a first region including:
a front surface display region having a first side meeting a second side at a corner of the front surface display region,
a first side surface display region extended bent from a first side of the front surface display region, and
a second side surface display region extended bent from a second side of the front surface display region;
and
a corner display region which extends bent from the corner of the front surface display region to the corner of the display device, and is between the first side surface display region and the second side surface display region in a direction along the outer edge of the display device, and
a display panel comprising:
a first light emitting element in the first region and including a first pixel electrode;
a second light emitting element in the corner display region and including a second pixel electrode;
a pixel defining layer in which a first opening and a second opening are defined corresponding to the first pixel electrode and the second pixel electrode, respectively;
the pixel defining layer including:
a first total area in the first region, and
a second total area in the corner display region;
a first spacer which is in the front display region and overlaps the pixel defining layer to define a first spacer area;
and
a second spacer which is in the corner display region and overlaps the pixel defining layer to define a second spacer area,
wherein among the front display region and the corner display region, a ratio of the first spacer area to the first total area in the front surface display region is greater than a ratio of the second spacer area to the second total area in the corner display region.
