A semitransparent reflective type liquid crystal display device is disclosed which comprises: first and second substrates facing to each other and sandwiching a liquid crystal layer therebeween; a backlight on an outer surface of the first substrate; an uneven layer being on an inner surface of the first substrate and having an uneven surface; a reflecting electrode being along the uneven surface and having a transparent portion substantially facing in a main viewing angle direction which is defined as a direction where the user's eye is mainly positioned. The transparent portion is in the inclined surface facing in the main viewing angle direction. Accordingly, when operating as a reflective type LCD, the quantity of the main external light which is incident on the transparent portion is decreased to improve the light reflectance.
