发明名称 Microlens array substrate, electro-optic device, and electronic apparatus
摘要 A microlens includes a lens center portion having a lens-curved surface and a lens circumference portion having a linear side surface. In the case where length of the side surface is taken as L1, length of an aperture is taken as Ax, an angle formed by a normal of the side surface and incident light on the microlens is taken as θ1, and an angle formed by the normal of the side surface and output light from the microlens is taken as θ2, a relational expression of Equation 1 is satisfied.;0<L1≤Ax⁢cos⁡(θ⁢1-θ2)cos⁢⁢θ2Equation⁢⁢1

主权项 1. A microlens array substrate comprising: a transparent substrate having a recess on one surface; a microlens that has a larger refractive index than the transparent substrate and that is in the recess; a light blocking portion that defines an aperture corresponding to the microlens in plan view; and an adjustment film formed on the microlens, wherein the microlens includes a lens center portion that is formed at a center of the microlens in plan view and that has a curved surface, and a lens circumference portion that is formed continuously with the curved surface and formed circularly surrounding the lens center portion in plan view, and that has a linear side surface in a cross-section that traverses the center of the lens, anda relational expression of Equation 1 described below is satisfied, in which a length of the linear side surface is taken as L1, a length of the aperture is taken as Ax, an angle formed by a normal of the linear side surface and incident light on the microlens is taken as θ1, and an angle formed by the normal of the linear side surface and output light from the microlens is taken as θ2:0<L1≤Ax⁢cos⁡(θ1-θ2)cos⁢⁢θ2Equation⁢⁢1 wherein the light blocking portion includes a first light blocking portion having a length of B1x and a second light blocking portion having a length of B2x, anda relational expression of Equation 2 described below is satisfied, in which a length from the microlens to the light blocking portion is taken as Lz:B1⁢x⁢tan⁢{π2-(θ1-θ2)}≤Lz≤(Ax+B1⁢x)⁢tan⁢{π2-(θ1-θ2)},Equation⁢⁢2and wherein the light blocking portion is formed on the adjustment film, and a thickness of the adjustment film is set approximately equal to the length Lz from the microlens to the light blocking portion.
