Liquid crystal display comprising an optical member having a chamfered portion and method for manufacturing the same

A liquid crystal display, comprising:

• a liquid crystal panel having a rectangular shape when seen from one side in a thickness direction;
• and
• an optical member that has a rectangular shape, has an optical axis, and is bonded to a surface on the one side or the other side in the thickness direction of said liquid crystal panel, wherein
• said optical member has a chamfered portion subjected to chamfering,
• said chamfering is C chamfering in which a chamfered shape of said chamfered portion is linear, and
• said chamfered shape is defined by x and y that satisfy relationships
• z=a·cos θ1+b·sin θ1−A0>0 (1)
• x=z/sin θ1=(a·cos θ1+b·sin θ1−A0)/sin θ1 (2)
• y=z/cos θ1=(a·cos θ1+b·sin θ1−A0)/cos θ1 (3)
• where z represents an amount of protrusion of the optical member that is not chamfered from a bonded object, a represents half (½) a length of a short side of an outer shape of the optical member, b represents half (½) a length of a long side of the outer shape of the optical member, θ1 represents a rotation angle of the optical member, A0 represents half (½) a length of a short side of an outer shape of the bonded object, x represents a chamfer length of the long side of the outer shape of the optical member, and y represents a chamfer length of the short side of the outer shape of the optical member.
