Abstract
The liquid crystal display device of the present invention can prevent the generation of the frame-like brightness difference at a portion which surrounds a light transmitting region. A pixel region formed over one substrate SUB1 which constitutes a liquid crystal display device includes a light transmitting region LTA which allows transmitting of light and a light reflecting region LRA which allows reflection of light. The light transmitting region LTA includes a first pixel electrode TPX formed of a conductive layer having the light transmitting property, while the light reflecting region LRA is formed of a second pixel electrode RPX formed of a conductive film having the non-light-transmitting property. A holding capacitance electrode CT which is connected to a holding capacitance line CL is formed below the second pixel electrode RPX. The holding capacitance electrode is formed of a material having light shielding property and is arranged such that the holding capacitance electrode is overlapped to a boundary portion between the light transmitting region LTA and the light reflecting region LRA, whereby the generation of the frame-like brightness difference at the portion which …
