Zusammenfassung:	To achieve HDR and low cost in addition to thinning of the present invention.SOLUTION: An optical member of the present invention includes: a main surface; a glass plate having an end face perpendicular to the main surface; and a lenticular part in which one or more light-focus structures are aligned, the light-focus structures extending in one direction on the main surface and having a light-focus property. The glass plate having an average internal transmissivity of 80% or more in a wavelength of 400-700 nm at 50 mm in length. A non-lenticular region is provided between a glass plate end part including the end face and an end part on a main surface of the lenticular part in a planar view, the non-lenticular region being a region in which the lenticular part is not provided and having a width of 0.3 mm or more to 30 mm or less.SELECTED DRAWING: Figure 1 【課題】薄型化に加えて、ＨＤＲ化または低価格化を実現する。【解決手段】本発明の光学部材は、主面と、該主面に対して垂直な端面とを有するガラス板と、主面上で一方向に延伸し、かつ集光特性を有する構造体である集光構造体が１つ以上並ぶ構造のレンチキュラー部とを備え、ガラス板は、５０ｍｍ長での波長４００〜７００ｎｍの平均内部透過率が８０％以上であり、平面視において端面を含むガラス板端部とレンチキュラー部の主面上の端部との間に、前記レンチキュラー部が設けられない領域である非レンチキュラー領域を有し、非レンチキュラー領域の幅が０．３ｍｍ以上３０ｍｍ以下である。【選択図】図１
