Display device employing light control member and display device manufacturing method
A liquid crystal is sealed with a sealing member between first and second transparent substrates, whereby a liquid crystal cell capable of transmitting ultraviolet light is produced. The liquid crystal cell is inserted into a mold into which an ultraviolet-setting resin is dropped and which is used to produce a light control member. The ultraviolet-setting resin is pressed to be bonded to the liquid crystal cell. In this state, ultraviolet light is irradiated to the liquid crystal cell in the mold from outside the mold. Thus, the ultraviolet-setting resin is set while bonding to the liquid crystal cell. Thereafter, the liquid crystal cell is removed from the mold. Consequently, the light control member is directly formed on the liquid crystal cell.
1. A method of manufacturing a display device that comprises a first transparent substrate having an electrode, a second transparent substrate having an electrode, a display cell having an electro-optic converting member, of which optical characteristic is varied with an electric action, sealed between said first and second transparent substrates, and a light control member made of an ultraviolet-setting resin and formed directly on the external side of said first transparent substrate opposite to the side thereof in contact with said electro-optic converting member, said display device manufacturing method comprising the steps of:
producing a display cell that can transmit ultraviolet light;
pouring an ultraviolet-setting resin in a mould engraved with line in the shape of a light control member; and
placing said display cell on said ultraviolet-setting resin in said mould so that said display cell will be superposed on said ultraviolet-setting resin, irradiating ultraviolet light to the side of said display cell opposite to the side thereof in contact with said ultraviolet-setting resin, allowing said ultraviolet-setting resin to set with the ultraviolet light transmitted by said display cell, and removing said display cell from said mould so as to thus form said light control member on said display cell.
2. A display device manufacturing method according to claim 1 , wherein said display cell placed in said mould is a single display cell.
3. A display device manufacturing method according to claim 1 , wherein said display cell placed in said mould is a set of display cells including a plurality of display cells.
4. A display device manufacturing method according to claim 3 , further comprising a step of cutting said set of display cells apart so as to produce a single display cell.
5. A method of manufacturing a display device that comprises a first transparent substrate having an electrode, a second transparent substrate having an electrode, a display cell having an electro-optic converting member, of which optical characteristic is varied with an electric action, sealed between said first and second transparent substrates, and a light control member made of an ultraviolet-setting resin and formed directly on the external side of said first transparent substrate opposite to the side thereof in contact with said electro-optic converting member, said display device manufacturing method comprising the steps of:
forming at least an electrode on a first transparent substrate;
pouring an ultraviolet-setting resin in a mould engraved with a line in the shape of a light control member;
placing said first transparent substrate, on which said electrode is formed, on said ultraviolet-setting resin in said mould so that said first transparent substrate will be superposed on said ultraviolet-setting resin;
irradiating ultraviolet light to the side of said first transparent substrate opposite to the side thereof in contact with said ultraviolet-setting resin, allowing said ultraviolet-setting resin to set with the ultraviolet light transmitted by said first transparent substrate, and removing said first transparent substrate from said mould so as to thus form said light control member on said first transparent substrate; and
bonding said first transparent substrate to a second transparent substrate so that said electro-optic converting member is sandwiched between said first and second transparent substrates.
