Liquid crystal display device

A liquid crystal display device, comprising:

• a liquid crystal display panel including a display area and a non-display area enclosing the display area;
• a light guide plate disposed under the liquid crystal display panel and having a polygonal plane shape including a first side, a second side, a third side, and a fourth side;
• a light source adjacent to the first side of the light guide plate;
• and
• a lower cover accommodating the liquid crystal display panel, the light guide plate, and the light source,
• wherein at least one of the second side, the third side, and the fourth side of the light guide plate overlaps the display area,
• wherein a width of the light guide plate is narrower than a width of the liquid crystal display panel,
• wherein the light guide plate extends continuously under the liquid crystal display panel,
• wherein at least a portion of the display area of the liquid crystal display panel does not overlap the light guide plate,
• wherein the lower cover includes an inclined portion, the inclined portion overlapping the liquid crystal display panel and not overlapping the light guide plate,
• wherein the liquid crystal display panel has a first surface facing the inclined portion of the lower cover and a second surface opposite the first surface of the liquid crystal display panel, and wherein the inclined portion of the lower cover has a first surface facing the liquid crystal display panel and a second surface opposite the first surface of the inclined portion, and
• wherein the inclined portion includes a first end closer to the light guide plate and overlapping the display area and a second end closer to an edge of the liquid crystal display panel and overlapping the non-display area, and wherein a distance between the second surface of the inclined portion and the second surface of the liquid crystal display panel gradually decreases from the first end to the second end of the inclined portion.
