Abstract

The present invention provides a display device, a method and apparatus for manufacturing the same, capable of suppressing degradation of display quality caused by bright spot defects. A display device (LCD) includes a first glass substrate (SUB1) and a second glass substrate (SUB2) that faces the first glass substrate and is located on a display surface side; a dimming portion (1) that covers thebright spot defect portion (133) as viewed from the display surface side is arranged inside at least one of the first glass substrate and the second glass substrate; the dimming portion has a lineartransmissive portion (7) having the transmittance of visible light higher than that of the other region (1 g) of the dimming portion as viewed from the display surface side; a cross section of the dimming portion in the thickness direction orthogonal to the longitudinal direction of the linear transmissive portion is in a folding line shape where a plurality of colored layers (2-1, 2-2) are continuous and bent, and the transmissive portion is located at the bent end portion (47) of the folding line.

Description

technical field [0001] The present invention relates to a display device, a manufacturing method thereof, and a manufacturing device. Background technique [0002] Among various display devices, for example, a liquid crystal display device drives the liquid crystal by applying an electric field generated between the pixel electrode and the common electrode to the liquid crystal layer sandwiched by a pair of substrates, thereby adjusting the transmission between the pixel electrode and the common electrode. The amount of light in the area for image display. [0003] Conventionally, for example, in liquid crystal display devices, there has been known a problem of so-called bright spot defects (also referred to as pixel defects) in which the display luminance of pixels is higher than desired. The bright spot defect occurs, for example, when a foreign matter is mixed between a pair of substrates during the manufacturing process of a liquid crystal display device, and the alignm...
