Abstract
To provide a liquid crystal display device to suitably perform color balance adjustment. For this, the liquid crystal display device includes pixel regions each including a light reflection portion and a light transmission portion on a liquid-crystal-side surface of one substrate out of respective substrates arranged to face each other in an opposed manner while sandwiching liquid crystal therebetween, wherein color filters are formed in pixel regions on a liquid-crystal-side surface of the other substrate out of the respective substrates, and each color filter is provided with an opening or notch at a part of a portion facing the light reflection portion in an opposed manner, material layers having a layer thickness substantially equal to a height of step generated by the color filters in regions facing the opening or notch of each color filter in an opposed manner on the liquid-crystal-side surface of one substrate.
