摘要： PROBLEM TO BE SOLVED: To provide a liquid crystal panel with little display unevenness by suppressing gap unevenness between a pair of glass substrates constituting the liquid crystal panel. SOLUTION: A pair of the glass substrates 1a, 1b with an uncured thermosetting sealant 2 arranged in between is wrapped in sheets 3a, 3b. The inside of the sheets 3a, 3b is nearly shut tight and depressurized. The glass substrates 1a, 1b and the sealant 2 are pressurized with differential pressure from atmospheric pressure via the sheets 3a, 3b maintaining a specified gap, and simultaneously the sheets 3a, 3b, the glass substrates 1a, 1b and the sealant 2 are heated with heaters 9a, 9b on positions separated from the sheets 3a, 3b and the sealant is cured. Thereby the gap between a pair of the glass substrates 1a, 1b is maintained. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a spacer scattering device, by which uniform spacer distribution is obtained with high efficiency while reducing the quantity of the spacers to be used, and by which the adherence of the spacers to the rear surface of the glass substrate is avoided. SOLUTION: The spacer scattering device is provided with a hollow electrode 7, electrically independently arranged inside a casing 1 constituting the device main body, having an open end at its lower part and having an internal insulation wall on its inside surface, a base 5 to mount a glass substrate, composed of an electric conductor connected with the ground, arranged on the lower side of the open end of the hollow electrode 7 and having a size included within an open region of the open end, a spacer scattering nozzle 3 arranged on the upper side of the hollow electrode 7, a spacer metering instrument 4 to measure the quantity of the spacers to be supplied to the spacer scattering nozzle 3, an air introducing port 11 to introduce air stream for supplying the spacers measured with the spacer metering instrument to the spacer scattering nozzle 3 and a controllable power source device 8 provided with a switching controller 8a to supply high voltage to the hollow electrode 7, or to connect it to the potential ground or to set it to an opened state.
