ABSTRACT:
The invention relates to an LCD panel for preventing the generation of blur due to ionic impurities. The LCD panel comprises a first substrate having a common electrode; a second substrate having an active area; a seal pattern along the periphery of said active area between said first substrate and said second substrate; a liquid crystal layer between said first substrate and said second substrate in said active area; and an electrode pattern between said seal pattern and said second substrate. Alternatively, the seal pattern has outwardly projecting corner portions. An electric field is generated between the electrode pattern and the common electrode so that the ionic impurities are prevented from penetrating into the active area, and the ionic impurities in liquid crystal are captured in the seal pattern portion to prevent the generation of blur due to ionic impurities.
