Display device and method of fabricating the same

A display device, comprising:

• a display substrate including a plurality of pixels that display an image, and a plurality of pixel pads connected to the pixels;
• a flexible film comprising a base film including a surface facing the pixel pads and an opposite surface facing the surface, and a plurality of output pads disposed on the surface of the base film and coupled to the pixel pads, respectively;
• and
• a rigid substrate disposed on the opposite surface of the base film and overlapping the output pads.

A method of fabricating a display device, comprising:

• providing a display panel including a plurality of pixels that displays an image, and a pixel pad portion connected to the pixels;
• providing a flexible film including a base film, an output pad portion, and a first substrate, wherein the base film includes a surface and an opposite surface facing each other, wherein the output pad portion is disposed on the surface of the base film and is coupled to the pixel pad portion of the display panel, and wherein the first substrate is disposed on the opposite surface of the base film and overlaps the output pad portion;
• performing a first aligning step including aligning an ultrasonic wave device to the first substrate;
• performing a first bonding step including bonding the pixel pad portion of the display panel to the output pad portion of the flexible film using the ultrasonic wave device,
• wherein the ultrasonic wave device is placed to be in contact with the first substrate.
