    摘要： Provided is a liquid crystal display device in which transmittance can be enhanced. The present invention provides a liquid crystal display device provided with a pair of substrates and a liquid crystal layer sandwiched between the pair of substrates. One of the substrates has a comb-shaped first electrode and a comb-shaped second electrode. The first electrode includes a first trunk portion and a first branch portion obliquely connected to the first trunk portion. The second electrode includes a second trunk portion and a second branch portion obliquely connected to the second trunk portion. The liquid crystal layer includes a p-type nematic liquid crystal that is vertically aligned with respect to the surfaces of the substrates when no voltage is applied. Each pixel has a blank portion of the second electrode having an acute angle-shaped blank portion and an obtuse angle-shaped blank portion that are mutually adjacent. The first branch portion has a specific branch portion disposed within the blank portion of the second electrode. The spacing between the specific branch portion and the second electrode at a portion that extends along the extension direction of the specific branch portion and that forms the acute angle-shaped blank portion is narrower, at least at the tip region of the specific branch portion, than the spacing between the specific branch portion and the second electrode at a portion that extends along the extension direction of the specific branch portion and that forms an obtuse angle-shaped blank portion.
