Abstract
The present invention discloses A transflective liquid crystal display device including a first substrate having a color filter; a second substrate having: a)a gate electrode formed on the second substrate; b) a first insulating layer formed on the exposed surface of the second substrate while covering the gate electrode; c) a semiconductor layer formed on the first insulating layer and over the gate electrode; d)a source electrode overlapping one end portion of the semiconductor layer; e) a drain electrode overlapping the other end portion of the semiconductor layer and spaced apart from the source electrode; f) a second insulating layer formed on the exposed surface of the first insulating layer while covering the source and drain electrode, having a first contact hole formed on a portion of the drain electrode; g) a pixel electrode formed on the second insulating layer and electrically connected with the drain electrode through the first contact hole; h) a third insulating layer on the pixel electrode and having a second contact hole over the first contact hole; and i) a reflective electrode formed on the third insulating layer and having a light transmitting hole and electrically connected with the pixel electrode through the second contact hole, the light transmitting hole transmitting light and covered by the pixel electrode; a liquid crystal display layer interposed between the first and second substrates; and a back light device for supplying light and located under the second substrate.
