Liquid crystal display device

A liquid crystal display device comprising:

• a liquid crystal panel;
• a backlight unit below the liquid crystal panel;
• a bottom cover including a horizontal surface, on which the liquid crystal panel and the backlight unit are placed, and a side surface perpendicular to the horizontal surface;
• a first guide panel coupled with the bottom cover, the first guide panel including a first vertical portion surrounding peripheral portions of the backlight unit and including a first horizontal portion that protrudes perpendicularly toward an inner side of the first vertical portion;
• and
• a second guide panel including a second vertical portion which is placed on and coupled to an outer side surface of the first vertical portion, and including a second horizontal portion which protrudes perpendicularly toward an inner side of the second vertical portion, the liquid crystal panel attached to a top surface of the second horizontal portion,
• wherein a rib protrudes perpendicularly to the first horizontal portion at a top surface of the first horizontal portion, and a rib groove, into which the rib is inserted, is formed at a bottom surface of the second horizontal portion.
