Liquid crystal display unit with spacer less damaged in washing solution and process for fabrication thereof

A liquid crystal display unit for producing visual images in an image producing area, comprising:

• a pair of substrate structures providing said visual image producing area and a frame area around said image producing area, and including electric components;
• a sealing layer extending along said frame area to define an inner space between the substrate structures of said pair, and formed of a first kind of material;
• liquid crystal filling said inner space, and varying a transparency depending upon electric signals on said electric components for producing said visual images;
• and
• a spacer for spacing said substrate structures from one another, and including a spacer wall structure extending along said frame area and encompassing at least a portion of the sealing layer, the spacer being formed of a second kind of material that is less eroded than said first kind of material in a washing solution used for washing residual liquid crystal from an outer surface of said pair of substrate structures.
