Microlens array substrate, electro-optic device, and electronic apparatus


A microlens array substrate includes a substrate having transparency and having a plurality of concave portions provided on a first surface to correspond to a plurality of pixels, and a lens layer having a different refractive index from a refractive index of the substrate, which is provided on the first surface of the substrate to fill in the plurality of concave portions, in which each of the plurality of concave portions has a flat portion arranged at the center portion, a curved surface portion arranged to surround the flat portion, an edge portion arranged to surround the curved surface portion and connected to the first surface of the substrate, and an angle between the edge portion and the first surface in a cross section passing through the center portion is smaller than an angle between a virtual curved surface obtained by extending the curved surface portion toward the first surface and the first surface.. .

Method and system for determining power of intraocular lens to be inserted


The present invention accurately predicts postoperative intraocular lens position on the basis of a shape image of the crystalline lens obtained by an optical interference tomographic imaging device. This makes it possible to reduce the postoperative refractive error and determine the power of the intraocular lens.

Determination of the effective lens position of an intraocular lens using aphakic refractive power


An ophthalmic method for determining a relationship between aphakic ocular power and estimated effective lens position (elp) of an intraocular lens (iol) to be implanted in a patient's eye. The method can be used to determine an estimate of the elp of an iol given the aphakic ocular power of the patient's eye, for example, without measurement of the corneal curvature or axial length of the patient's eye.

Method of manufacturing microlens array substrate, microlens array substrate, electro-optic device, and electronic


There is provided a method of manufacturing a microlens array substrate with improved manufacturing yield and high quality, the method including: forming a groove part along an outer edge of a first area on a surface of a substrate; forming a mask layer to cover a side of the surface, forming a plurality of openings in the first area, and forming openings along the outer edge of the first area; performing isotropic etching on the substrate through the mask layer, forming a plurality of recesses in the first area, and forming recesses across a boundary part between the first area and the groove part; removing the mask layer from the substrate; forming a light transmission material layer that has a refractive index, which is different from a refractive index of the substrate, to cover the side of the surface of the substrate and to bury the plurality of recesses; and planarizing an upper surface of the light transmission material layer.. .

Retardation element, liquid crystal display device, and projection display device


Provided is a retardation element, including: a transparent substrate; a retardation imparting antireflection layer; a first birefringent layer; and a second birefringent layer which has approximately the same average thickness as that of the first birefringent layer and contacts the first birefringent layer such that an angle formed between a first line segment representing the principal axis of refractive index anisotropy of the first birefringent layer and a second line segment representing the principal axis of refractive index anisotropy of the second birefringent layer is neither 0° nor 180° when the first line segment and the second line segment are projected on the transparent substrate such that an end a of the first line segment at a side of the transparent substrate and an end b of the second line segment at a side of the transparent substrate coincide with each other.. .
