ABSTRACT:
The present invention relates to a liquid crystal display. The relation of ∈ (permittivity). sg(r) (resistivity) between a liquid crystal layer, an aligning layer or an overcoat for preventing poor images is established. An LCD according to the present invention includes a first panel including a plurality of devices thereon and an aligning layer formed on the entire surface thereof, a second panel opposite to the first panel and including an overcoat and an aligning layer sequentially formed on the entire surface thereof, and a liquid crystal layer interposed between the first pane) and the second panel. It is preferable that the aligning layer, the liquid crystal layer and the overcoat satisfy the relation (a). An LCD according to another embodiment includes a first panel including a plurality of devices thereon and an aligning layer formed on the entire surface thereof, a second panel opposite to the first panel and including an overcoat and an aligning layer sequentially formed on the entire surface thereof, and a liquid crystal layer interposed between the first panel and the second panel. It is preferable that the liquid crystal and the overcoat satisfy the relation (b).
