ABSTRACT:
A liquid crystal display includes: first and second substrates on which a display area and a non-display area are defined and a plurality of pixels are defined at the display area; a pixel electrode formed at each pixel on the first substrate; a plurality of first attachment improving protrusions formed at the non-display area along edges of the display area on the first substrate and made of the same material as the pixel electrode on the layer on which the pixel electrode is formed; a common electrode formed at least on a display area of the second substrate; a plurality of second attachment improving protrusions formed on the non-display area of the second substrate and branched off from the common electrode; and a sealant formed between the first and second substrates such that the sealant is attached with the first and second attachment improving protrusions, and having conductivity, wherein the common electrode receives a common voltage via the sealant and the first attachment improving protrusions.
