Abstract: A display device includes: a plurality of first color filters not intersecting a non-linear portion with at least a part of an outer shape of a display region being non-linear, a plurality of second color filters at least part of which intersects the non-linear portion, a first region with the plurality of first color filters disposed, a second region with the plurality of second color filters disposed, a first light blocking portion partitioning the plurality of first color filters, a second light blocking portion partitioning the plurality of second color filters, and a spacer. An overlapping area of the second light blocking portion with respect to the plurality of second color filters is larger than that of the first light blocking portion with respect to the plurality of first color filters. A distribution density of the spacer in the second region is lower than that in the first region.

Abstract: A surface-coated cutting tool including a tool substrate containing WC crystal grains and insulating grains, and a coating layer composed of a multiple nitride of Ti, Al, and V and disposed on the surface of the tool substrate. The multiple nitride is represented by a compositional formula: TiaAlbVcN satisfying the following relations: 0.25?a?0.35, 0.64?b?0.74, 0<c?0.06, and a+b+c=1 wherein each of a, b, and c represents an atomic proportion. The coating layer is characterized by exhibiting a peak attributed to a hexagonal crystal phase and a peak attributed to a cubic crystal phase as observed through X-ray diffractometry.

Abstract: To provide a surface-coated cutting tool exhibiting excellent wear resistance in a high-speed cutting process and having prolonged service life. The surface-coated cutting tool includes a tool substrate containing WC crystal grains and insulating grains, and a coating layer composed of a multiple nitride of Ti, Al, and V and disposed on the surface of the tool substrate. The multiple nitride is represented by a compositional formula: TiaAlbVcN satisfying the following relations: 0.25?a?0.35, 0.64?b?0.74, 0<c?0.06, and a+b+c=1 (wherein each of a, b, and c represents an atomic proportion). The coating layer is characterized by exhibiting a peak attributed to a hexagonal crystal phase and a peak attributed to a cubic crystal phase as observed through X-ray diffractometry.

Abstract: To improve the adhesion resistance and wear resistance of a surface-coated cutting tool. The surface-coated cutting tool includes a tool substrate, and a single-component coating layer composed of a composite nitride of Cr (chromium), Al (aluminum), and V (vanadium) and disposed on the surface of the tool substrate. The composite nitride is characterized by being represented by a compositional formula: CraAlbVcN satisfying the following relations: 0.11?a?0.26; 0.73?b?0.85; 0<c?0.04; and a+b+c?1 (wherein a, b, and c each represent an atomic proportion). The single-component coating layer has both a hexagonal phase and a cubic phase.
