Abstract: Provided is a display device including a display panel which allows a curvature portion thereof to be narrowed near a terminal portion even when circuit blocks are arranged in the curvature portion. For a data line in the form of a polyline consisting of a plurality of short straight line segments in a first curvature portion 12a of a display panel 10, as the distance from a terminal portion 16 increases, the slant angle of each straight line segment increases, the number of data lines d decreases, and hence the width of a data line area decreases. Accordingly, the number of unit circuit blocks 70 in a parallel circuit block 80 disposed in a circuit area can be increased by widening the circuit area in proportion to the decrease in the width of the data line area.

The method includes winding a thermosetting resin-impregnated fiber bundle around a liner so as to form an uncured fiber-reinforced resin layer thereon, first heating in which the uncured fiber-reinforced resin layer is locally heated at a first temperature so as to leach the thermosetting resin out of the uncured fiber-reinforced resin layer to form the surface resin layer, and the surface resin layer is cured to have cracks generated therein, and second heating in which the tank is entirely heated at a second temperature lower than the first temperature, so that the fiber-reinforced resin layer and surface resin layer are entirely cured, so as to obtain the tank with the surface resin layer locally having cracks generated therein.
