    Abstract: A light guide pate includes: a light guide member with a light incident surface and first and second principal surfaces; and first and second protrusions formed on at least one of the first and second principal surfaces. When the first principal surface is viewed in a normal direction, a distance between the light incident surface and the second protrusion is larger than a distance between the light incident surface and the first protrusion; each of the first and second protrusions has a shape, a length of which in an orthogonal direction orthogonal to a propagation direction of light incident from the light incident surface increases monotonously in the propagation direction; and a minimum value of the length of the second protrusion in the orthogonal direction is larger than a maximum value of the length of the first protrusion in the orthogonal direction.
