Abstract
The present disclosure provides a glass plate including a main surface having a plurality of minute deformed portions which are recesses or projections, wherein, where an average value of lengths of two sides adjacent to each other of a minimum quadrilateral with four right angles surrounding each minute deformed portion is defined as a dimension, an average value of the dimensions of the plurality of deformed portions is 3.2 to 35.5 μm. The glass plate satisfies a condition a1 that a ratio of deformed portions A1 having the dimensions of 0.5 to 3.0 μm with respect to the plurality of deformed portions in terms of number is less than 5%, and/or a condition d1 that a coefficient of variation of the dimensions is 40% or less. This glass plate is suitable for suppressing sparkle and is highly practical, when disposed on an image display device.
