Abstract
To control the positioning of a spacer more accurately in a liquid crystal display device to prevent display defects due to incorrect positioning in a display region. To provide a liquid crystal display device with higher image quality and reliability, and to provide a method for manufacturing the liquid crystal display device with high yield. In a liquid crystal display device, a region onto which a spherical spacer is discharged is subjected to liquid-repellent treatment in order to reduce the wettability with respect to a liquid in which the spherical spacer is dispersed. The liquid (the droplet) does not spread over the liquid-repellent region and is dried while moving the spherical spacer toward the center of the liquid. Thus, incorrect positioning shortly after discharging, which has been caused by the loss of control in the liquid, can be corrected by moving the spherical spacer while drying the liquid.
