Abstract
A liquid crystal display (LCD) device maintains a cell gap and prevents press defects via the use of ball spacers. The liquid crystal display device includes first and second substrates facing each other, a plurality of first spacers, a plurality of second spacers, and a liquid crystal layer filled between the first and second substrates. The first spacers are formed between the first and second substrates at portions of a black matrix layer of the second substrate. The first spacers include a plurality of first balls with a first diameter and a first solid to aggregate the first balls. The second spacers are formed at portions of the black matrix layer between the first and second substrates. The second spacers include a plurality of second balls with a second diameter 0.2 to 0.6 μm smaller than the first diameter and a second solid to aggregate the second balls.
