Abstract: According to an aspect, a method for manufacturing a display device includes: producing an array substrate in which first electrodes are formed on a first light-transmitting base member; producing a counter substrate in which a second electrode is formed on a second light-transmitting base member; forming a sealing portion on the array substrate or the counter substrate; dropping, inside the sealing portion, polymer-dispersed liquid crystals that contain photocrosslinkable monomers and liquid crystal molecules in gaps between the monomers; bonding the array substrate to the counter substrate, and forming a liquid crystal layer in which the polymer-dispersed liquid crystals have been dropped; and curing the liquid crystal layer by irradiating the liquid crystal layer with ultraviolet rays while a voltage is applied to the first and second electrodes. At the producing the counter substrate, projections of the second electrode that project from the second electrode toward the first electrodes are formed.

Abstract: To improve the display quality of a display device, the display device includes a display section and a frame section surrounding a periphery of the display section. A substrate in the display device includes a conductor pattern constituting a circuit section and an insulating film serving as an organic film covering the conductor pattern. The insulating film extends to a peripheral edge of the substrate. A slit, which penetrates the insulating film in a thickness direction, is formed in a corner part of the insulating film. The slit is formed at a position not overlapping the circuit section.
