摘要： Disclosed are a reflective and transflective liquid crystal display device and its manufacturing method, which can raise light efficiency by removing a depressed part in a reflective device without forming a capacitor contact hole in a storage capacitor. The reflective liquid crystal display device includes: a plurality of gate lines and data lines intersecting on a first substrate, the gate line and the data line defining pixel areas; a thin film transistor formed at the intersection of the gate line and the data line, the thin film transistor including a gate electrode, a semiconductor layer, a source electrode and a drain electrode; a capacitor lower electrode of a storage capacitor formed on the same plane as the gate line; an capacitor upper electrode formed integrally with the drain electrode on the capacitor lower electrode; a first insulation film inserted between the capacitor upper electrode and the capacitor lower electrode; and a thin film transistor array substrate connected with the drain electrode and including the reflective electrode formed at the pixel area.
