摘要:
To improve reliability of a liquid crystal display apparatus using an upper substrate, the upper substrate to be combined with a lower substrate includes a transparent electrode and a first spacer. The lower substrate includes a display region and a driving region surrounding the display region to provide a drive signal to the display region. A liquid crystal layer is interposed between the upper substrate and the lower substrate. The first spacer is formed on the transparent electrode corresponding to the driving region to protect the driving region. The first spacer is disposed such that a rubbing having a rubbing direction of the upper substrate does not end at the first spacer. Thus, a corner white phenomenon that is caused by impurities stacked at a side portion of the first spacer may be reduced.
