Display device and method of manufacturing the same

A display device comprising:

• a base member including a first area at which an image is displayed and a second area which extends from the first area in a first direction and at which the image is not displayed;
• a display element layer with which the image is displayed, disposed on the base member in the first area thereof;
• a driving circuit electrically connected to the display element layer and with which the display element layer is controlled to display the image, disposed on the base member in the second area thereof;
• a signal line electrically connecting the display element layer in the first area to the driving circuit in the second area;
• and
• a support member on which is supported the base member including the display element layer, the driving circuit and the signal line thereon, defining:
• a recessed portion disposed in the bending area;
• a first bump and a second bump spaced apart from each other in the first direction to define the recessed portion therebetween;
• and
• extensions extending away the first bump and the second bump, to opposing ends of the support member, respectively,
• wherein
• along the first direction, the first bump of the support member is disposed closer to the display element layer than the second bump of the support member, and
• in cross-section, a size of the first bump is different from a size of the second bump.

A method of manufacturing a display device, the method comprising:

• providing a preliminary display device comprising:
• a display panel which displays an image, comprising a pixel with which the image is displayed, the pixel disposed on a top surface of a base member of the display panel,
• wherein the base member includes a first area in which the pixel is disposed and at which the image is displayed, and a second area which extends from the first area in an extending direction and at which the image is not displayed;
• and
• a base support member facing a bottom surface of the base member which is opposite to the top surface thereof, in the first and second areas of the base member;
• at a portion of the base support member which corresponds to the second area of the base member:
• first pressing the base support member at a first press area thereof, by using a heating block to deform the base support member and form a first bump and a preliminary bump spaced apart from each other along the extending direction;
• and
• second pressing the base support member at a second press area spaced apart from the first bump, by using the heating block to deform the base support member and form from the preliminary bump a second bump spaced apart from the first bump along the extending direction;
• and
• bending the second area of the display panel and the portion of the base support member corresponding thereto with reference to a bending axis after the second pressing, to dispose the first bump and the second bump of the base support member each overlapping the first area of the display panel, and form the display device.
