Display device and electronic device including the same

A display device comprising:

• a display unit;
• a frame supporting the display unit, the frame being under the display unit;
• a case accommodating the display unit and the frame;
• and
• a hinge assembly including a hinge cover, a first hinge module, and a second hinge module, the first hinge module is seated on an inner surface of the hinge cover, a lowermost end of the display unit is rotatably coupled to the first hinge module, the second hinge module is seated on the inner surface of the hinge cover, and an uppermost end of the display unit is rotatably coupled to the second hinge module,
• the frame is configured to rotate around a frame rotational axis in the first hinge module,
• the case is configured to rotate around a case rotational axis in the second hinge module,
• an inter-axis distance is in a range of about 400 μm to about 600 μm,
• a frame rotational axis distance is defined as a distance between the frame rotational axis and an outer surface of the hinge cover,
• a case rotational axis distance is defined as a distance between the case rotational axis and the outer surface of the hinge cover, and
• the inter-axis distance is obtained by subtracting the case rotational axis distance from the frame rotational axis distance.
