Abstract
Disclosed herein are a liquid crystal display (LCD) device and a method for manufacturing the same, capable of preventing problems (i.e., movement of balls, damage to the surfaces that face spacers upon application of predetermined pressure, and variation in cell gap) associated with the use of the ball spacers. The liquid crystal display device includes a first substrate and a second substrate facing each other, a spacer formed on the first substrate, wherein the spacer includes a plurality of balls and a solid to aggregate the balls together and adhere the balls to the first substrate, a hard coating layer formed on the second substrate facing the spacer, and a liquid crystal layer filled between the first substrate and the second substrate.
