Abstract
A liquid crystal device includes an elemental substrate provided with a silicon oxide alignment layer on the front surface side thereof. Silanol groups of the alignment layer are bound to an organic silane polymer layer by silane coupling treatment. The silane coupling treatment also forms an organic silane polymer layer on the rear surface side of the elemental substrate. This organic silane polymer layer is a layer having a higher hydrophilicity than the organic silane polymer layer. A light-transmitting plate bonded to the rear surface side of elemental substrate with an adhesive layer is thus unlikely to separate.
Claims18
A liquid crystal device comprising:
- a first substrate;
- a second substrate opposing the first substrate;
- and
- a liquid crystal layer between the first substrate and the second substrate,
- wherein the first substrate includes a first substrate body having a first surface opposing the second substrate and a second surface opposite the first surface, the first surface being provided with a first inorganic alignment layer and a first organic silane polymer layer that are formed in this order, the second surface being provided with a second organic silane polymer layer which is the same as the first organic silane polymer layer, a first adhesive layer, and a first light-transmitting plate that are formed in this order, and
- wherein a portion of the second organic silane polymer layer in contact with the first adhesive layer outside a display region is at least partially a first layer having a higher hydrophilicity than the second organic silane polymer layer of the display region.
A method for manufacturing a liquid crystal device including a first substrate, a second substrate opposing the first substrate, a frame-like sealing member surrounding a display region and bonding the first substrate and the second substrate together, and a liquid crystal layer between the first substrate and the second substrate, the method comprising:
- forming a first inorganic alignment layer over a first surface of a first substrate body and then treating the first substrate body with a silane coupling agent, thereby simultaneously forming a first organic silane polymer layer at the first surface and a second organic silane polymer layer at a second surface opposite the first surface;
- modifying at least a part of a portion of the second organic silane polymer layer outside the display region into a first layer having a higher hydrophilicity than the second organic silane polymer layer of the display region;
- and
- bonding a first light-transmitting plate with a first adhesive layer in contact with a region including the first layer.
