  • Publication number: 20200333657
    Abstract: A display panel includes paired substrates including plate faces each divided into an active area and a non-active area and facing each other across an interior space, a sealing portion interposed between the paired substrates and arranged in the non-active area in such a manner as to surround the interior space for sealing the interior space, an alignment film disposed on at least the display area on one of the paired substrates, an insulating film disposed on the one of the paired substrates farther from the interior space than the alignment film and arranged across the active area and the non-active area, and a recess portion disposed in the non-active area on the insulating film in such a manner as to overlap the sealing portion and including at least a first recess and a second recess configured to extend in such a manner as to surround the first recess.

  • Patent number: 10754203
    Abstract: A liquid crystal panel includes a pair of substrates, a seal part between the pair of substrates and in a non-display region to surround and seal the liquid crystal layer, a planarizing film and a second interlayer insulating film being insulating films on the array substrate across a display region and the non-display region, an alignment film on the array substrate closer to the liquid crystal layer than the planarizing film and the second interlayer insulating film are, the alignment film being disposed across the display region and the non-display region, and a defining part formed of the planarizing film and the second interlayer insulating film, which are insulating films, the defining part being disposed at a position overlapping with the seal part in the non-display region, to define an alignment film non-disposed region where the alignment film is not disposed.

  • Patent number: 10025141
    Abstract: An array board includes a glass substrate including a display area and a non-display area, an organic insulation film disposed over a range of the display area and the non-display area, an array board side alignment film disposed on the organic insulation film, a film forming area restricting portion disposed in the non-display area and recessed in a part of the surface of the organic insulation film, and an alignment film material storing portion disposed closer to the display area than the film forming area restricting portion in the non-display area and recessed in a part of the organic insulation film. An angle formed by at least a part of a surface of the alignment film material storing portion and a normal line of the glass substrate is greater than an angle formed by a side surface of the film forming area restricting portion and the normal line.

  • Publication number: 20160048045
    Abstract: An array board 1311b includes a first conductive film, a second conductive film, an insulator, an alignment film 1311e, and at least two inclined portions 48, 49. The second conductive film is disposed above the first conductive film and at least a portion of the second conductive film overlap the first conductive film in a plan view. The insulator is disposed between the first conductive film and the second conductive film. The insulator includes a contact hole formed at a position overlapping the first conductive film and the second conductive film in a plan view and connects the second conductive film to the first conductive film. The alignment film 1311e is disposed above the second conductive film. The alignment film 1311e includes a portion that overlaps the contact hole in a plan view and a portion that does not overlap the contact hole in a plan view. The inclined portions 48, 49 are formed at an edge of the contact hole in the insulator.

  • Publication number: 20150355516
    Abstract: An array board 11b includes a first conductive film, a second conductive film, an insulator, and an alignment film. The second conductive film is disposed above the first conductive film and includes at least a portion that overlaps the first conductive film in a plan view. The insulator is held between the first and the second conductive films. The insulator includes a contact hole at a position overlapping the first and the second conductive films in a plan view for connecting the second conductive film to the first conductive film. The alignment film 11e is disposed above the second conductive film and includes a portion overlapping the contact hole and a portion not overlapping the contact hole in a plan view. The bending portion 43 is defined by at least a portion of an edge of the contact hole in the insulator. The bending portion bends toward an inner side of the contact hole such that an outer angle of the bending portion in a plan view is a reflex angle.

  • Publication number: 20100255222
    Abstract: A display element that includes substrates each having a thin film layer formed by applying a thin film layer composition thereon by an ink-jet method, in which, in the formation of the thin film layers, streaky display unevenness does not develop along a direction in which an ink-jet head discharges the composition having the shape of dots aligned on straight lines from the nozzles. In the liquid crystal display element 1 including an array substrate 5 including an alignment film 8, and a color filter substrate 3 including an alignment film 7, the substrates 5 and 3 being used in a pair, the dots on the alignment films 7 and 8 are aligned such that an interval between the straight lines on the alignment film 8 is displaced by half an interval from an interval between the straight lines on the alignment film 7.
