Abstract
A curved LCD device includes first and second substrates; gate and data lines in a display area on the first substrate and defining a pixel region; a thin film transistor connected to the gate and data lines; a color filter layer in the pixel region; pixel and common electrodes on the color filter layer; first light-blocking layers in the display area over the first substrate; a second light-blocking layer in a non-display area over the first substrate; first and second column spacers in the display area on the second substrate, wherein the first column spacer has a first height, and the second column spacer has a second height; and a third column spacer in the non-display area on the second substrate and having the second height, wherein the third column spacer is in point-contact with the second light-blocking layer when an external force is applied.
