In a display apparatus, a light guide plate includes a chamfered corner portion that defines a light incident surface. A light source unit is arranged adjacent to the light incident surface to provide the light to the light guide plate through the light incident surface. A display panel receives light from the light guide plate to display an image. A receiving container includes sidewalls and a bottom portion to accommodate the light guide plate and the light source unit. At least one sidewall adjacent to the corner portion is divided into a first part and a second part that may be coupled to or separated from each other. Thus, the light guide plate and the light source unit may be easily accommodated in the receiving container, thereby improving an assembling efficiency.

In a display apparatus according to one or more embodiments, a boosting circuit boosts an input voltage to a backlight driving voltage, and a backlight unit receives the backlight driving voltage to generate light. A backlight driving circuit controls the boosting circuit in response to a dimming signal and compensates a plurality of feedback voltages fedback from the backlight unit to output a panel driving voltage. A panel driving circuit receives the panel driving voltage from the backlight driving circuit to output a data voltage corresponding to an image signal and receives a gate driving voltage to generate a gate voltage. A display panel displays an image in response to the gate voltage and the data voltage. Accordingly, a number of the boosting circuits for the display apparatus may decrease, thereby reducing a manufacturing cost of the display apparatus.
