Liquid crystal display device

A liquid crystal display (LCD) device comprising:

• a liquid crystal display panel;
• a backlight unit under the liquid crystal display panel and including a reflective plate, a light guide plate and a plurality of optical sheets;
• and
• a bottom plate accommodating the backlight unit,
• wherein the bottom plate includes a shielding member and an alignment hole, and
• wherein the bottom plate has a protruding portion having the alignment hole formed therein,
• wherein the bottom plate includes a base portion having a first area and a second area surrounding the first area and side wall portions extending from a periphery of the base portion,
• wherein the reflective plate, the light guide plate and the plurality of optical sheets are sequentially stacked on the base portion corresponding to the first area,
• wherein the side wall portions are perpendicularly disposed on the base portion in the second area,
• wherein the protruding portion is parallel to the side wall portions in the second area,
• wherein the shielding member is disposed on the base portion surrounding the reflective plate, the light guide plate and the plurality of optical sheets, and
• wherein the shielding member is in contact with side wall portions, sides of the reflective plate, the light guide plate and the plurality of optical sheets and an upper surface of the base portion.

An apparatus comprising:

• a display panel having at least one alignment mark;
• a backlight unit under the display panel and including a reflective plate, a light guide plate and a plurality of optical sheets;
• a metallic support structure including a base portion having a first area and a second area surrounding the first area and side walls that support said display panel and the backlight unit;
• a light shield member at corresponding inner portions of said support structure;
• and
• one or more alignment posts, having respective alignment holes therethrough, located at respective portions of said support structure adjacent to the side walls thereof and received through respective portions at said light shield member,
• wherein the reflective plate, the light guide plate and the plurality of optical sheets are sequentially stacked on the base portion corresponding to the first area,
• wherein said alignment posts and said at least one alignment mark facilitate attachment of said display panel to said support structure during the alignment process,
• wherein the side walls are extended from a periphery of the base portion,
• wherein the side walls are perpendicularly disposed on the base portion,
• wherein the alignment posts are parallel to the side walls,
• wherein the light shield member surrounds the reflective plate, the light guide plate and the plurality of optical sheets of the backlight unit, and
• wherein the light shield member is in contact with the side walls, sides of the reflective plate, the light guide plate and the plurality of optical sheets and an upper surface of the base portion.
