Abstract: A liquid crystal panel has a hole allowing light to pass through or to be shielded, and suppresses an influence on the light passing through the hole. A liquid crystal panel includes: a first substrate having a flat plate shape; a second substrate arranged to face the first substrate; a light shielding film spreading along an inner surface of the second substrate and having the hole formed therein; a plurality of spacers arranged on an outer side of a region between the substrates, the region corresponding to the hole; and a liquid crystal sandwiched between the first substrate and the second substrate. The second substrate is held such that a distance from the first substrate becomes larger as coming closer to the hole, and the portion corresponding to the hole has a shape protruding in a direction extending from the first substrate to the second substrate.

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.
