In a method of the present invention for holding a substrate in a vacuum, a glass substrate () is held by an adhesive pad () or an adhesive sheet, both of which are made from a material containing a diene based resin, whereby an adhesive agent is prevented from remaining on the substrate, and the adhesive sheet can be detached with ease from the substrate after assembling the substrates.

Method for holding substrate in vacuum

A liquid crystal display panel includes two substrates fixed together by a seal member with their main surfaces opposed to each other, liquid crystal sealingly stored in a region surrounded by the two substrates and the seal member, and a plurality of columnar spacers arranged in a region surrounded by the two substrates and the seal member. A number density of the columnar spacers in a low-density region near the inner side of the seal member is smaller than that in a high-density region inside the low-density region. The substrate with the spacer has the substrate and the spacer formed on the substrate. The spacer has at least a first spacer portion, and a second spacer portion formed above the first spacer portion. An upper portion of the first spacer has a larger diameter than a bottom of the second spacer portion.

A printing plate includes, on the printing surface of a raised part, grooves passing through from one side to another thereof. Preferably, the grooves are parallel to each other and equally spaced apart. More preferably the raised part is in the shape of a nearly-rectangular frame, and the grooves are provided such that one side of the near-rectangle and the longitudinal direction of the grooves form an angle of 45&#xb0;.
