Display device, method of manufacturing the same, and electronic device

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.
