Abstract: The present invention relates to a glass plate which is provided with a first main surface, and a second main surface which faces the first main surface. An antiglare portion and a non-antiglare portion are provided to the first main surface. The average lengths (RSm) of elements of roughness curves of the antiglare portion and the non-antiglare portion are respectively 1 μm or higher. The difference between the RSm of the antiglare portion and the RSm of the non-antiglare portion is 100 μm or lower.
