An accelerated process for preparing an O-methyl phenol comprising reacting a phenol with dimethyl carbonate in the presence of a catalyst selected from 1,8-diazabicyclo5. The assembly has a plurality risers having vertically spaced substantially horizontal portions with the risers being movable between an extended position for use and a retracted position for storage. Further, the third passivation film 45 prevents penetration of moisture and oxygen from the TFTs, and suppress degradation of the EL element 203 by dispersing the heat generated by the EL element 203.
