摘要： Provided is a glass sheet capable of suppressing the generation of stray light when used as a light-guiding plate of an eyeglass-type device such as a head-mounted display. The glass sheet is a glass sheet (1) including a first principal surface (1a) and a second principal surface (1b) opposed to each other and an end surface (1c) connecting the first principal surface (1a) and the second principal surface (1b) to each other, wherein the glass sheet (1) has a refractive index (nd) of from 1.6 to 2.2 and has an R shape in at least part of the end surface (1c), and the end surface (1c) has a surface roughness Ra of 100 nm or less.

摘要： Provided is a light guide plate which, when used as a light guide plate of a glasses-type device such as a wearable device for AR/MR, is capable of enhancing color reproducibility of an image. A light guide plate 10 includes a glass plate 1, and a resin layer 2 formed at a main surface of the glass plate 1. The difference in Abbe number νd between the glass plate 1 and the resin layer 2 is less than 10. The refractive indices nd of the glass plate 1 and the resin layer 2 are 1.7 or greater and the difference between the refractive indices nd is 1.0 or less.
