Abstract
The present invention discloses a liquid crystal display device including a first insulating substrate having: a) a buffer layer formed on the first substrate; b) an inter-layer insulating film formed on the buffer layer, the inter-layer insulating film having an etching portion, the etching portion is etched; c) a semiconductor island formed on a portion of the buffer layer corresponding to the etching portion; d) data lines formed on the semiconductor island; e) gate lines arranged in a direction perpendicular to the data lines; f) switching elements arranged near cross points of the gate and data lines, each of the switching element having a gate electrode, a source electrode and a drain electrode, the gate electrode extending from the gate line, the source electrode extending from the data line; and g) pixel electrodes formed on a region defined by the gate and data lines, the pixel electrode connecting with the drain electrode, the pixel electrode overlapping an end portion of the data line, the adjacent two pixel electrodes spaced apart from each other; a second insulating substrate having a color filter; and a liquid crystal layer interposed between the first and second insulating substrates.
