ABSTRACT:
A rigid liquid crystal display cell is provided with superior productivity and durability. The liquid crystal display cell includes upper and lower substrates, two kinds of spacers with different heights, and a liquid crystal layer held between a gap defined by the upper and lower substrates. The upper and lower substrates are sealed at the peripheral by sealant. The liquid crystal material is put into the gap through an injection inlet. The substrate are pushed by the pressure to discharge superfluous liquid crystal material from the cell. An end seal closes the inlet but the width of the end seal to be sucked is kept in a predetermined range when the pressure applied to the substrates is removed.
