PURPOSE: A liquid crystal display device is provided to easily attach a dual-surface attachment tape by aligning the tape on a main support precisely in reference to protrusions formed on the main support, thereby preventing the damage of optical sheets. CONSTITUTION: A liquid crystal display device includes a main support in which a blacklight unit having a plurality of optical sheets, a light guide panel and a reflecting sheet, and a liquid crystal panel are stacked, a guide panels surrounding the edges of the blacklight unit and the liquid crystal display panel, and a case top for surrounding edges of the liquid crystal display panel and the guide panel. The main support includes first a second stepped grooves(54a,54b). The first grooves have pins(54c) inside and the second grooves are formed higher than the first grooves with protrusions(66) of a predetermined height corresponding to a height of the optical sheets and a dual-surface attachment tape.
