Abstract

A first substrate () of a liquid crystal display device () includes a TFT () that includes an oxide semiconductor layer (a). A second substrate () includes a color filter layer () and a light-shielding layer (). The light-shielding layer has a first TFT light-shielding portion () for each row in at least a blue pixel column, and a second TFT light-shielding portion () every n rows (n represents an integer of 2 or more) in a pixel column in which at least one type of color filter other than blue color filters is provided, the second TFT light-shielding portion having a larger area than the first TFT light-shielding portion. A columnar spacer () is arranged so as not to overlap the first TFT light-shielding portion but to overlap the second TFT light-shielding portion.
