Abstract

In an alignment regulating layer, a plurality of regulation regions is defined in plan view perpendicular to the surface of the alignment regulating layer, and the plurality of regulation regions includes at least one first regulation region, at least one second regulation region, and a third regulation region fitted between the first regulation region and the second regulation region. The alignment regulating direction in the first regulation region is a first regulating direction, and the alignment regulating direction in the second regulation region is a second regulating direction that is different from the first regulating direction. In the third regulation region, the alignment regulating direction continuously changes from the first regulating direction to the second regulating direction from a portion contacting the first regulation region toward a portion contacting the second regulation region.

Claims (30)

1. A display, comprising:

a liquid crystal layer containing liquid crystal molecules, and

an alignment regulating layer having a surface contacting the liquid crystal layer, and having characteristics of regulating alignment of the liquid crystal molecules,

wherein the alignment regulating layer has a plurality of regulation regions defined in plan view perpendicular to the surface,

wherein the plurality of regulation regions includes at least one first regulation region, at least one second regulation region, and a third regulation region fitted between the first regulation region and the second regulation region,

wherein in the alignment regulating layer, a direction in which alignment of the liquid crystal molecules is regulated is an alignment regulating direction,

wherein the alignment regulating direction in the first regulation region is a first regulating direction,

wherein the alignment regulating direction in the second regulation region is a second regulating direction that is different from the first regulating direction, and

wherein the third regulation region, the alignment regulating direction continuously changes from the first regulating direction to the second regulating direction from a portion contacting the first regulation region toward a portion contacting the second regulation region.

2. The display of claim 1 ,

wherein the alignment regulating layer contains photoreactive molecules exhibiting characteristics of regulating the alignment direction of the liquid crystal molecules by irradiation with light;

and further comprising:

a substrate made of a resin, and

a reflective layer provided between the substrate and the alignment regulating layer.

3. A method of manufacturing a display, comprising the steps of:

forming an alignment regulating layer having a surface, and

forming a liquid crystal layer containing liquid crystal molecules on the surface of the alignment regulating layer, wherein

the forming of an alignment regulating layer includes forming a plurality of regulation regions in the alignment regulating layer in plan view perpendicular to the surface, the plurality of regulation regions including at least one first regulation region, at least one second regulation region, and a third regulation region fitted between the first regulation region and the second regulation region,

in the alignment regulating layer, a direction in which alignment of the liquid crystal molecules is regulated is an alignment regulating direction,

the alignment regulating direction in the first regulation region is a first regulating direction,

the alignment regulating direction in the second regulation region is a second regulating direction that is different from the first regulating direction, and

in the third regulation region, the alignment regulating direction continuously changes from the first regulating direction to the second regulating direction from a portion contacting the first regulation region toward a portion contacting the second regulation region.

4. The method of manufacturing a display of claim 3 , wherein the forming of an alignment regulating layer comprises the steps of:

forming a precursor layer containing photoreactive molecules;

applying first light through a mask comprising a first mask element for the first regulation region and a second mask element for the second regulation region to form a third precursor region in a portion where the precursor layer aligns with a portion including a boundary that is between the first mask element and the second mask element in a direction in which the precursor layer aligns with the mask, to form a first precursor region in a portion where the precursor layer aligns with the first mask element, the portion excluding the third precursor region, and to form a second precursor region in a portion where the precursor layer aligns with the second mask element, the portion excluding the third precursor region; and

applying second light to the precursor layer to forming the first regulation region from the first precursor region, to form the second regulation region from the second precursor region, and to form the third regulation region from the third precursor region.

5. The method of manufacturing a display of claim 4 , wherein

the mask comprises the first mask element and the second mask element,

the first mask element has a larger transmissivity with respect to the first light than in the second mask element,

the first mask element and the second mask element each have a rectangular shape, and the first mask element and the second mask element are adjacent to each other, as viewed from a direction in which the mask aligns with the precursor layer.
