Abstract: A liquid crystal display device includes a transmissive liquid crystal display panel which is disposed on a front side of a display medium that is capable of effecting variable display, and a pair of polarizer plates which are disposed on outer surfaces of the liquid crystal display panel. The liquid crystal display panel includes an image display section which is configured to be capable displaying an image, a substantially rectangular transmissive display section which corresponds to a region where the display medium is disposed, and a light shield section which is disposed between the image display section and the transmissive display section. Each of the polarizer plates includes a substantially rectangular aperture corresponding to the region where the display medium is disposed, and an edge which defines the aperture is positioned on the light shield section of the liquid crystal display panel.

Abstract: In matrix array substrate for flat-panel display devices or the like in which a repair circuit for connecting a defected pixel electrode and next electrode in a tandem is disposed between the two pixel electrodes, a contact hole for connecting one of connector electrodes of the repair circuit to one of the pixel electrodes is disposed within contours of a scanning line. Meanwhile, in a matrix array substrate for normally white mode flat-panel display devices, an island metal pattern is disposed within the contours of a scanning line and within a storage-capacity-forming portion extended from one of the two electrodes. The island metal pattern is formed simultaneously with signal line and has a scanning-line-wise size larger than width of the scanning line.

Abstract: Counter substrate (color filter substrate) 2 is provided with light-shielding-layer pattern 22 to cover thin-film-transistors 13 in display region 5 and light-shielding-layer pattern 23 at edge portion out of display region to prevent light from leaking from display region 5. Inspection is not carried out to detect defects 21 of light-shielding-layer pattern 23 when counter substrate 2 is assembled, or done to detect them but counter substrate 2 is used in assembling a liquid crystal display device without repair. After defects 21 are detected and their positions are identified, laser light is irradiated to defects 21 on the condition that the liquid crystal display device is kept assembled. Such irradiation of the laser light disturbs alignment of alignment film 25 in portions corresponding to defects 21 in order to prevent the leakage of light from defects.
