The V light curve of eclipsing binary LD355 was analyzed by using the latest version of Wilson Program in order to derive photometric elements of this system. Since no spectroscopic mass ratio is available, the q-search method was applied to yield the preliminary range of mass ratio in order to search for the final solution. The solution was performed by assuming detached (mode 2) and semi-detached (mode 5) configurations, since no classification of the system based on the shape of light curve is possible . The solution in mode 5 leads to an acceptable model. The present solution reveals that LD355 has a photometric mass ratio q=0.178 and is a semi-detached binary with the secondary component filling the Roche lobe.
