PROCESS FOR PRODUCING DISPLAY UNIT AND DISPLAY UNIT PRODUCTION APPARATUS

摘要

A display unit is produced by bonding an upper substrate and a lower substrate together. There is provided an apparatus comprising at least sealing agent application section (13) for applying a sealing agent to a substrate; liquid display material application section (14) for applying a liquid display material to a substrate; and substrate bonding section (15) for bonding an upper substrate and a lower substrate together, wherein each of the upper substrate and lower substrate has a thickness of 10 to 500 µm and an elastic modulus of 10 MPa to 100 GPa, and wherein when the side having multiple pixels constitutes the upper substrate while the side furnished with a driving circuit constitutes the lower substrate, their linear expansion coefficients referred to as A and B, respectively, 1.0 = A/B < 1.5, and wherein the elastic modulus of the sealing agent is referred to as C, 1.0 GPa < C < 10.0 GPa. Further, when the area ratio D refers to the proportion of space defined by void between liquid display material and sealing agent drawn on one of the substrates, 0.9 = D < 1.0. Still further, when E refers to the ratio of height of liquid display material to height of sealing agent, 0.1 = E = 0.5. In the stage of substrate bonding in which continuous upper and lower substrates are bonded together, the tilt angle of, against one of the substrates, the other substrate is 5° or greater, and the bonding is performed under ordinary pressure while pressurizing at 1 N/cm<SUP>2</SUP> or higher.
