Claim:
1. A liquid crystal display device, comprising: a lower substrate and an upper substrate bonded to each other and having a display region and a non-display region defined thereon; a gate line on the lower substrate in one direction and a data line intersecting with the gate line to define a pixel region; a thin film transistor at the intersection between the gate line and the data line; a pixel electrode on the pixel region of the lower substrate, and electrically connected to the thin film transistor; a planarization layer on the lower substrate, the thin film transistor, and the pixel electrode, the planarization layer having: a black matrix on the upper substrate; a color filter layer on the upper substrate between the adjacent black matrixes; partition walls on the upper substrate and forming a space corresponding to the seal pattern insertion groove; a column spacer to maintain a cell gap between the upper substrate and the lower substrate; a liquid crystal layer interposed between the lower substrate and the upper substrate; and a seal pattern between the seal pattern insertion groove and the partition walls located within the non-display region defined on the lower substrate and the upper substrate wherein the plurality of anti-spreading grooves are parallel to the pattern insertion groove on a side of the seal pattern insertion groove away from the display region.
