Abstract
A liquid crystal display device that reduces the likelihood of liquid crystal misalignment and driving errors is presented. The liquid crystal display device also improves color reproductively. The device includes a first substrate, and second substrate, and a liquid crystal layer placed between the first substrate and the second substrate. The first substrate includes a gate line and a data line that define a pixel region, a thin film transistor provided at an intersection area of the gate line and the data line, an organic film formed on the thin film transistor and having a depressed portion, a reflective film formed on the organic film, a black matrix, a color filter layer formed in the pixel region, and a pixel electrode formed on the color filter layer. The color filter layer has a different thickness in the depressed portion than in the rest of the pixel region.
