Disclosed is a silicon-base liquid crystal projection television receiver, especially a panel assembly of silicon-base liquid crystal engine. It includes: a panel; a sponge attached in the front of the panel; a panel fixer assembling the front of the sponge to the panel; a QWP fixer, QWP, gum assembled in turn on the fixer; a mask attached on the sponge between the fixer of the panel and the sponge. Through the panel fixer between the panel assembly and the mask between the sponge the sponge is easy to assemble, at the same time, it is easy to cover the gap between the panel fixer and the panel. The uniform distribution between the panel fixer and the panel is realized along with the sponge to adopt a definite form through the mask, thereby the foreign matter is prevented to enter the gap between the panel fixer and the panel. |
