The rollable display is composed of a plurality of layers including an organic light emitting layer,

The processor is

In response to detecting the occurrence of the first event, at least some pixels among a plurality of pixels disposed on an edge of the organic light emitting layer to be recognizable through a side surface of the housing to emit light.
7. The method of claim 6,

Further comprising a sensor disposed inside the housing,

The processor is

determining at least one of an inclination angle of the rollable electronic device and a direction in which the rollable electronic device faces by using the data sensed by the sensor;

In response to detecting the occurrence of the first event, based on at least one of an inclined angle of the rollable electronic device and a direction toward which the rollable electronic device faces, at least some pixels disposed at an edge of the rollable display A rollable electronic device that controls to emit light.
7. The method of claim 6,

At least a portion of an edge of the rollable display is formed in an arc shape.
7. The method of claim 6,

The rollable display is composed of a plurality of layers including an organic light emitting layer,

At least one of the plurality of layers includes at least one optical element for changing a traveling direction of light output from the organic light emitting layer.
7. The method of claim 6,

The processor may control the at least some pixels disposed at an edge of the rollable display to provide information on a state of the rollable electronic device.
A rollable display of a rollable electronic device, comprising:

At least a portion of an edge of the rollable display is formed in an arc shape,

The rollable display may include outputting at least a portion of light in a lateral direction of the rollable display in a state in which the rollable display is retracted to be wound a plurality of times inside the housing of the rollable electronic device.
13. The method of claim 12,

The rollable display controls to emit light of at least some pixels disposed at an edge of the rollable display to output at least a portion of light in a lateral direction of the rollable display.
13. The method of claim 12,

The rollable display is composed of a plurality of layers,

an edge of at least one of the plurality of layers is bent to form at least a portion of an edge of the rollable display in an arc shape;
13. The method of claim 12,

The rollable display is composed of a plurality of layers,

At least one of the plurality of layers includes at least one optical element for changing a traveling direction of light output from the organic light emitting layer.
