Abstract

A metallic back case ( 40 ) arranged on the back side of a main liquid crystal panel ( 20 ) included in a double-sided display liquid crystal module has an opening ( 42 ) that corresponds to a sub liquid crystal panel ( 60 ). A resin frame ( 50 ) is removably fitted in the opening ( 42 ), and the sub liquid crystal panel ( 60 ) is fitted to the resin frame ( 50 ). Thus, the sub liquid crystal panel ( 60 ) is kept out of direct contact with the back case ( 40 ).
