A transflective liquid crystal display device includes an upper array substrate that has a gate line, a data line crossing the gate line while being insulated, an organic passivation film pattern overlapped with the data line, and a pixel electrode formed to overlap the data line with the organic passivation film pattern therebetween. A lower array substrate faces the upper array substrate with a liquid crystal layer therebetween and that has a dispersion film which disperses an external light, a reflection pattern which is formed on the dispersion film and in a reflection area, a color filter layer formed on the reflection pattern and the dispersion film, and a common electrode which covers the color filter layer. A backlight unit irradiates light to the lower array substrate.
