Abstract: A first laser irradiation, in which an amorphous silicon film is irradiated with a first laser beam for transformation of the amorphous silicon film to a microcrystalline silicon film, and a second laser irradiation, in which a second laser beam moves along a unidirectional direction with the microcrystalline silicon film as a starting point for lateral crystal growth of growing crystals constituting a crystallized silicon film, are carried out to form a microcrystalline silicon film and a crystallized silicon film alternately along the unidirectional direction.

Abstract: A display device substrate including: a circuit portion; a first organic insulating film disposed on an upper layer side of the circuit portion; a second organic insulating film disposed on an upper layer side of the first organic insulating film; an alignment film disposed on an upper layer side of the second organic insulating film; and a film formation area regulating portion including a recess in a part of the second organic insulating film and disposed to regulate a film formation area of the alignment film and to overlap the circuit portion.

Abstract: A liquid crystal panel includes two substrates, an outer light-shielding portion, an inner light-shielding portion, and spacers. The substrates are bonded to each other. The outer light-shielding portion is disposed outer than an outer periphery of area display area in which an image is displayed between the substrates. The inner light-shielding portion is disposed inner than an inner periphery of the display area between the substrates. The spacers are disposed between the substrates. The spacers include outer spacers and at least one inner spacer. The outer spacers are disposed to overlap the outer light-shielding portion. The at least one inner spacer is disposed to overlap the inner light-shielding portion.

Abstract: A display panel includes: a display area in which an image is to be displayed; a non-display area in which no image is to be displayed; a first mark that is arranged in the non-display area; a second mark that is arranged in the non-display area on a layer different from a layer on which the first mark is arranged and is adjacent to or superimposed on the first mark in a plan view; a light-transmitting portion that is arranged in the non-display area in such a manner as to overlap at least the first mark in a plan view; and a light-shielding portion that is arranged in the non-display area on a side opposite to the light-transmitting portion with respect to the first mark and the second mark and overlaps the light-transmitting portion in a plan view.

Abstract: A display device includes a display section including a first substrate and a second substrate, the display section displaying an image according to an electric signal, a terminal pad electrically connecting a conductor to a signal source or a ground node, and an information code expressing optically-readable information. The second substrate has a substrate overlapping area overlapping the first substrate in a plan view and a substrate non-overlapping area not overlapping the first substrate. At least a part of the terminal pad serves as a light-transmitting portion. The terminal pad and the information code are disposed in the substrate non-overlapping area on one plate surface of the second substrate such that they overlap each other in a plan view, with the light-transmitting portion covering the information code from above.
