Display apparatus

A display apparatus comprising:

• a display panel which displays an image;
• a top chassis and a bottom chassis which house the display panel, the bottom chassis comprising a plurality of hooks attached to an inner surface thereof;
• a plurality of main printed circuit board (PCB) units that extend in a longitudinal direction and which are detachably hooked into the plurality of hooks to mount the main PCB units to the bottom chassis, each of the main PCB units comprising a plurality of light source packages that emit light onto a rear of the display panel;
• and
• a sub-PCB that is detachably electrically and physically installed across the plurality of main PCB units and that provides power to the plurality of main PCB units,
• wherein each of the plurality of hooks is formed in a single body with the bottom chassis,
• wherein the main PCB comprises a conductive pattern layer to supply power to the plurality of light source packages,
• wherein the conductive pattern layer comprises a first region and a second region, and an area of the first region is larger than an area of the second region,
• wherein each of the light source packages comprises a light source, a first electrode, and a second electrode spaced apart from the first electrode in a width direction of the main PCB, and the light source is installed on the first electrode,
• wherein the first region contacts the first electrode of a light source package and the second region contacts the second electrode of the light source package,
• wherein the second region is entirely separated from the first region by an insulation layer.
