Abstract
The present disclosure relates to a liquid crystal display device and a fabricating method thereof. The device includes a thin film transistor formed on a lower substrate, a pixel electrode formed on the lower substrate, a planarization layer formed on an entire surface of the lower substrate, a black matrix formed on the upper substrate, a color filter layer formed on a upper substrate, partition walls formed on the upper substrate and forming a space corresponding to a seal pattern insertion groove, a liquid crystal layer interposed between the lower substrate and the upper substrate, and a seal pattern inserted between the seal pattern insertion groove located on the non-display region of the lower substrate and the upper substrate and the partition walls.

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 formed 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 formed on the intersection between the gate line and the data line;
- a pixel electrode formed on the pixel region of the lower substrate, and electrically connected to the thin film transistor;
- a planarization layer having a seal pattern insertion groove formed on the non-display region of the lower substrate having the pixel electrode and the thin film transistors;
- a black matrix formed on the upper substrate;
- a color filter layer formed on the upper substrate between the adjacent black matrixes;
- partition walls formed on the upper substrate and forming a space corresponding to the seal pattern insertion groove formed on the lower substrate;
- 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 inserted between the seal pattern insertion groove and the partition walls located on the non-display region of the lower substrate and the upper substrate.
A method of fabricating a liquid crystal display device comprising:
- providing a lower substrate and an upper substrate having a display region and a non-display region defined thereon;
