A liquid crystal display device (1) includes an upper substrate (100), a lower substrate (200) and a liquid crystal layer (300) between the two substrates (100, 200). The upper substrate (100) has a common electrode (110). The lower substrate (200) has pixel electrodes (200) and there are many unit pixel regions defined on the lower substrate (200). Each unit pixel region has a transmissive region (230) and a reflective region (240). Liquid crystal molecules of the liquid crystal layer (300) are aligned perpendicularly to the surfaces of the substrates (100, 200) when no voltage is applied. There are many irregular protrusions (220) on the pixel electrodes (210). In the reflective region (240), there is a reflective metal layer (250) on the irregular protrusions (220).
