    Abstract: The present invention discloses a substrate, a LCD panel, a LCD device and a method of sealant coating, wherein the substrate of said LCD panel comprises one or more quadrangular display areas surrounded and formed by sealant; the starting points of the sealant around said display area overlap the ending points to form an overlap section; wherein said overlap section is positioned at a corner of said display area. Because the application connections are just at the corner, the extra sealant can be directly cut off during cutting; in addition, the contamination by material extrusion after pressing caused by overly thick sealant coating at the connections can be avoided; and the man-hour of multiple cuttings can be reduced. Because the sealant overlap section is at the corner of the display area and will not diverge from the display area, the difficulty in controlling the width of the lines is solved.

    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.
