摘要： Provided is a method of manufacturing a display device including a louver that is capable of changing viewing angle. The method includes: a first step of forming a first electrode layer to drive the louver on a first main face of a first substrate; a second step of forming a resin layer on the first electrode layer; a third step of forming louver grooves to contain electrophoretic particles and dispersion medium in the resin layer; a fourth step of forming a sealing layer having a flat top face on the resin layer having the louver grooves in such a manner that the sealing layer closes the louver grooves; a fifth step of forming color filters on the sealing layer; and a sixth step of forming a second electrode layer to drive the louver on the sealing layer.

摘要： A liquid crystal display device includes a first liquid crystal display panel including a first light-transmitting substrate (thickness T2≤0.3 mm), a substrate, a first liquid crystal, a first polarizing plate having a second main surface that is adhered to the first light-transmitting substrate; an adhering layer provided on a first main surface of the first polarizing plate; and a second light-transmitting substrate (thickness T3≤0.3 mm) adhered to the first main surface by the adhering layer (thickness T1≤0.15 mm). An adhesion parameter α is 1.04 or less when a maximum height of an unevenness of the first main surface 0.0005 mm or less, and the adhesion parameter α is 0.43 or less when the maximum height of the unevenness of the first main surface is greater than 0.0005 mm and 0.001 mm or less.

摘要： A substrate laminating apparatus, including a first vacuum chamber including a first opening; a first table provided inside the first opening for holding a first substrate; a second vacuum chamber including a second opening; a second table provided inside the second opening for holding a second substrate, wherein the substrates are laminated by reducing a pressure in a closed space formed by having the first opening faced with the second opening. The apparatus also includes a vacuum evacuation unit connected to the first vacuum chamber or the second vacuum chamber and performs reduced-pressure evacuation of the closed space. When there is a direction along which priority is given on lamination precision when laminating the first and second substrates, and the direction is defined as a lamination precision priority direction, a reduced-pressure evacuation direction done by the vacuum evacuation unit is a direction different from the lamination precision priority direction.
