Backlight unit and liquid crystal display device including the same

A liquid crystal display (LCD) device, comprising:

• a backlight unit, comprising:
• a supporting case supporting a supporting side wall having a receiving space;
• a light guide plate placed in the receiving space of the supporting case;
• a light source member irradiating light on a light incident surface prepared in a side surface of the light guide plate;
• an optical sheet member disposed on the light guide plate;
• and
• a plurality of holder members disposed at certain intervals between the supporting side wall and some side surfaces of the light guide plate except the light incident surface, the holder members being deformed in shape by thermal deformation of the light guide plate;
• a liquid crystal display panel disposed on the backlight unit;
• a guide frame disposed in the supporting case of the backlight unit, and supporting a rear edge portion of the liquid crystal display panel;
• a rear cover receiving the supporting case, and surrounding a side surface of the guide frame;
• and
• a front cover coupled to the rear cover to surround a front edge portion and side surface of the liquid crystal display panel.
