Abstract: A display apparatus includes a light source generating a light, a display panel receiving the light from the light source and including a display area displaying an image and a non-display area disposed adjacent to the display area, and first and second optical sheets disposed under the display panel. Each of the first and second optical sheets includes a body portion overlapped with the display area and a wing portion connected to one side portion of the body portion in the first direction to overlap with a portion of the non-display area. A length of the wing portion of the first optical sheet in the second direction is shorter than a length of the wing portion of the second optical sheet in the second direction, and the wing portion of the first optical sheet is entirely overlapped with the wing portion of the second optical sheet.

Abstract: A display device includes: a display panel which displays an image with light and a drive unit which is electrically connected to the display panel and drives the display panel. The drive unit includes a drive circuit board and a drive circuit film. The drive circuit board overlaps the display panel, generates a drive signal to drive the display panel and defines a receiving hole therein. The drive circuit film electrically connects the display panel to the drive circuit board and is bent from the display panel toward the drive circuit board. The drive circuit film includes a driver chip which provides a control signal in response to the drive signal from the drive circuit board. The driver chip is received in the receiving hole defined in the drive circuit board.
