Disclosed are a transflective liquid crystal display device and a method for manufacturing the same, capable of simply forming a reflection section and driving a liquid crystal display device with a transmission mode or a transflective mode by using the same array substrate. After preparing the upper substrate, the thin film transistor is formed in the switching region of the upper substrate. Color resin is coated on the thin film transistor, and is developed to form the color filter. The light-shielding layer is formed on the color filter to prevent current from being leaked from the thin film transistor. The lower substrate is formed in such a manner that the lower substrate is spaced by a predetermined distance from the upper substrate. The reflection plate is formed on the reflection section. The transparent electrode is formed on the reflection plate.
