Provided is a method for manufacturing a highly reliable display device. The method includes steps of providing a first layer, a first insulating layer, an electrode, and a second insulating layer over a first surface of a first substrate; removing a part of the second insulating layer to provide a first opening; providing a display element and a second layer over the second insulating layer; providing a third layer and a third insulating layer over a second surface of a second substrate; removing part of the third layer and part of the third insulating layer to provide a second opening; overlapping the first substrate and the second substrate with a bonding layer positioned therebetween such that the first surface and the second surface face each other and the first opening and the second opening have an overlap region; separating the first substrate and the first layer from the first insulating layer; providing a third substrate such that the first insulating layer and the third substrate overlap with each other; separating the second substrate, part of the bonding layer, part of the second layer, and the third layer from the third insulating layer; and providing a fourth substrate such that the third insulating layer and the fourth substrate overlap with each other.

A liquid crystal alignment member for spatial light phase modulation includes: a silicon substrate; a base portion including pixel electrodes arranged in a matrix with a period of 3 m or less; a lattice-shaped wall structure configured by a dielectric material; a base layer connected to the lattice-shaped wall structure; and a plurality of liquid crystal-filling microspace separated from each other by the lattice-shaped wall structure, wherein the lattice-shaped wall structure is arranged at least between adjacent pixel regions; the liquid crystal-filling microspace includes a shape anisotropy in a first axial direction and a second axial direction in a plane parallel to the base portion; when W.sub.A is a space width of the first axial direction and W.sub.B is a space width of the second axial direction, W.sub.A is smaller than W.sub.B; and a base groove extending to the second axial direction is formed in the base layer.

A method of transferring a thin film is a method of transferring a thin film formed on a first substrate to a second substrate, the method including: allowing the first substrate to come into contact with a liquid to swell the first substrate; allowing the second substrate and the thin film to come into contact with each other via the liquid; and drying the liquid to allow the thin film to adhere to the second substrate.

Embodiments of improved methods are provided to form ordered structures on a surface of a substrate using direct self-assembly (DSA) of ionic liquid crystals (ILCs). More specifically, various embodiments of methods are provided to control the phase of an ordered structure formed on a substrate surface via self-assembly of ILCs having cation head groups, alkyl tail groups having a plurality of hydrocarbons and anions. In the embodiments disclosed herein, the phase of the ordered structure is controlled by replacing the hydrogen (H) atoms of the hydrocarbons included the alkyl chain with larger sized functional groups. Adding larger sized functional groups to the alkyl chain changes the phase of the ordered structure by: (a) increasing the separation between the hydrophilic (cation) and hydrophobic (alkyl tail) groups of the ILCs, and (b) changing the orientation of alkyl tails within the tail groups of the self-assembled ILCs.
