1. A display device comprising:
a display panel including
a display section in which a plurality of pixels are arrayed in a matrix, the display section including a pixel portion and a frame portion that surrounds the pixel portion,
a plurality of scan lines that select pixels,
a plurality of signal lines that supply image signals to the pixels,
a substrate,
color filters that are arranged above the substrate,
a light-shielding layer covering the scan lines and the signal lines in the pixel portion and the frame portion, and
a polarizer overlapping the color filters and the light-shielding layer; and
a cover plate mounted on the display panel, the cover plate having
a first cover portion overlapping the frame portion and
a second cover portion other than the first cover portion, a light transmittance of the first cover portion being lower than a light transmittance of the second cover portion,
wherein
the light-shielding layer has a separation location in the frame portion, and
a light-shielding material,
the separation location is located between a first part of the light-shielding material and a second part of the light-shielding material in the light-shielding layer,
some of the color filters overlap the separation location,
the color filters include a red color filter, a blue color filter, and a green color filter,
none of the color filters are provided in the separation location, and
the first cover portion of the cover plate overlaps the separation location of the light-shielding layer, such that the first cover portion, the substrate, and the separation location are stacked in this order.
