A position structure of a liquid crystal display for positioning a display panel in a display cover is disclosed. The position structure includes a position piece, a position protrusion, and a position breach. The position piece is placed between the display panel and the display cover to absorb a tolerance between the display panel and the display cover. The position protrusion is formed on a sidewall of the display cover and the position breach is formed on the position piece. The position breach is disposed corresponding to the position protrusion. The position protrusion may couple with the position breach to fix the position piece between the display panel and the display cover.
