Electronic device comprising flexible display and method for controlling electronic device

An electronic device comprising:

• a wireless communication module comprising wireless communication circuitry;
• a first housing;
• a second housing slidably coupled to the first housing;
• a flexible display including a first display area exposed to outside in a slide-in state based on movement of the second housing in a first direction and a second display area exposed to outside in a slide-out state based on the movement of the second housing in a second direction, wherein the flexible display includes a touch panel to receive a user touch input;
• memory comprising one or more storage media storing instructions;
• and
• at least one processor comprising processing circuitry,
• wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
• display a first application on the first display area in the slide-in state,
• in response to receiving a notification related to a second application from an external electronic device through the wireless communication module, display the notification at a first position of the first display area and a state change icon at a second position of the first display area, wherein the state change icon is an icon to transition the electronic device from the slide-in state to the slide-out state,
• in case that the user touch input is received with respect to the notification at the first position, display an execution screen of the second application on the first display area in the slide-in state, the execution screen corresponding to the received notification, and
• in case that the user touch input is received with respect to the state change icon at the second position, switch the electronic device from the slide-in state to the slide-out state and display the execution screen of the second application on the second display area.
