Abstract
In a liquid crystal display device into which a phase difference film is incorporated on the color filter substrate side, the phase difference film can be formed more easily than the prior art. A pair of substrates and a liquid crystal display panel having a liquid crystal sandwiched between the above described pair of substrates are provided in such a manner that the above described liquid crystal display panel has a number of subpixels, each subpixel in the above described number of subpixels has a transmission portion and a reflection portion, and a first substrate from among the above described pair of substrates has: a light blocking film which is formed at least in a border between the above described transmission portion and the above described reflection portion and at least has a portion which surrounds only the above described reflection portion; an orientation film for orienting the phase difference film formed on the above described light blocking film; a phase difference film formed inside the portion surrounded by the above described light blocking film on the above described orientation film; a color filter formed on the above described phase difference film; and a flattened film formed on the above described color filter.
