Abstract: A substrate for display comprises one surface, the other surface, a first area (folding area) and a second area (non-folding area). A first hole passing through the one surface and the other surface is formed on the first area. A 1-1 groove is formed on one surface of the first area in the direction from the one surface to the other surface. A 1-2 groove is formed on the other surface of the first area in the direction from the other surface to the one surface. A 2-1 groove is formed on one surface of the second area in the direction from the one surface to the other surface. A 2-2 groove is formed on the other surface of the second area in the direction from the other surface to the one surface. The 1-1 groove and 1-2 groove and the 2-1 groove and 2-2 groove do not overlap each other in the thickness direction of the substrate for display.
