SEOUL, Oct 25 (Reuters) - South Korean flatscreen maker LG Display posted on Wednesday its sixth consecutive quarterly loss, hit by continued weakness in premium TV demand.

The Apple supplier posted an operating loss of 662 billion won ($491.11 million) for the July-September quarter versus a loss of 759 billion won a year earlier.

The result was slightly worse than a forecast loss of 610 billion won from 15 analysts polled by LSEG SmartEstimate, weighted toward analysts who are more consistently accurate. ($1=1,347.9600 won) (Reporting by Joyce Lee and Heekyong Yang; Editing by Clarence Fernandez)
