Backlight assembly and liquid crystal display

A backlight assembly comprising:

• a light guide panel including a first surface and a second surface adjacent to the first surface;
• a light source unit disposed along the first surface to emit light onto the first surface, the light source unit comprising:
• at least one light emitting diode (LED) to face the first surface, and
• a circuit board to apply electric signals to the at least one LED such that the at least one LED is disposed on a surface of the circuit board facing the first surface and the surface of the circuit board extends across the entire first surface;
• a stepped part disposed at a corner connecting the first surface to the second surface;
• and
• a connector disposed on the surface of the circuit board facing the first surface and within a space defined by a width and a depth of the stepped part to provide an electrical connection to the light source unit,
• wherein the first surface of the light guide panel includes a first area facing the light source unit to receive the light from the light source unit, and a second area cut into the first surface with respect to the first area, extended outward from the first area, and disposed adjacent to at least one of the second surface of the light guide panel and the stepped part.

A liquid crystal display (LCD) comprising a liquid crystal panel that displays images, and a backlight assembly that supplies light to the liquid crystal panel, wherein the backlight assembly comprises:

• a light guide panel having at least one cut part;
• a light source unit arranged along a first lateral side of the light guide panel, the light source unit comprising:
• at least one light emitting diode (LED) to face the first lateral side, and
• a circuit board to apply electric signals to the at least one LED such that the at least one LED is disposed on a surface of the circuit board facing the first lateral side and the surface of the circuit board extends across the entire first lateral side;
• a lower cover having at least one supporting part corresponding to the cut part of the light guide panel;
• at least one stepped part disposed at a lateral corner of the light guide panel, being extended from borders with incident surfaces facing the light source unit;
• and
• a connector disposed on the surface of the circuit board facing the first lateral side and within a space defined by a width and a depth of the stepped part to provide an electrical connection to the light source unit.

A display device, comprising:
