Abstract

An in-plane-switching mode liquid crystal display device is disclosed. The LCD device includes: first and second substrates opposite to each other; a liquid crystal layer interposed between the first and second substrates; a passivation film formed on the first substrate in which a thin film transistor is disposed; pixel and common electrodes arranged alternately with each other; and a first alignment film formed on the pixel and common electrodes. The liquid crystal layer and the passivation film are formed to have lower non-resistances than that of the first alignment film.

Description

technical field [0001] The present disclosure relates to a liquid crystal display device, and more particularly, to an in-plane switching mode liquid crystal display device adapted to prevent an afterimage problem. Background technique [0002] This application claims priority from Korean Patent Application No. 10-2008-00136536 filed on December 30, 2008, the entire contents of which are hereby incorporated by reference. [0003] Nowadays, a liquid crystal display (LCD) device, which is a next-generation display device, has been in the spotlight. This status quo is due to the fact that LCD devices have low power consumption, high portability, technology density, high added value, and other features. In order to provide an image to a user, an LCD device is configured to utilize light transmittance that varies with molecular alignment of liquid crystals. [0004] Among many LCD devices, a twisted nematic (TN) mode LCD device is mainly used because of its simple configuration...
