摘要： A display device in the present disclosure includes the following: a substrate; a plurality of source bus lines extending in a first direction above the substrate; a plurality of semiconductor layers extending in the first direction above the plurality of source bus lines; and a first groove-shaped recess extending in a second direction crossing the first direction, the first groove-shaped recess constituting a first contact hole extending from above the plurality of source bus lines to the plurality of source bus lines. Each of the plurality of semiconductor layers is disposed along a surface of the first groove-shaped recess so as to cross the first groove-shaped recess, and each of the plurality of semiconductor layers is electrically connected to each of the plurality of source bus lines on the bottom surface of the first groove-shaped recess.

摘要： A first substrate (10) of a liquid crystal display device (100) includes a TFT (2) that includes an oxide semiconductor layer (2a). A second substrate (20) includes a color filter layer (22) and a light-shielding layer (21). The light-shielding layer has a first TFT light-shielding portion (21t1) for each row in at least a blue pixel column, and a second TFT light-shielding portion (21t2) 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 (40) is arranged so as not to overlap the first TFT light-shielding portion but to overlap the second TFT light-shielding portion.
