Diversified manufacturer 3M Co. warned Friday that its results would miss expectations because of weaker-than-expected demand for optical film used in liquid crystal displays (LCD).
    Companies from manufacturers to retailers had expected a burst of orders for LCD flat-panel televisions ahead of the World Cup soccer games, but 3M said demand did not meet those hopes.
    The warning was the latest sign of trouble in the LCD marketplace and pulled down the shares of other players, including LG. Philips LCD Co.
    3M said it expected to report second-quarter sales of about ＄5.7 billion. Analysts had expected the company to report sales of ＄5.72 billion, according to Reuters Estimates.
    The company expects to earn ＄1.14 to ＄1.17 a share in the second quarter. For the year, 3M said it expected to earn ＄4.55 to ＄4.65 a share.
    On average, analysts expected the company to report per-share earnings of ＄1.17 for the quarter and ＄4.67 for the year.
    The company said the whole electronics industry had "overestimated demand for LCD televisions in anticipation of the FIFA World Cup." That resulted in rising inventory levels, especially for desktop monitors, 3M said, and had "significantly impacted" sales of its optical films.
    3M, also known for its Scotch tape and Post-it notes, said the marketwide weakness in demand was aggravated internally by higher-than-expected costs as the company increased the outputs.
    The shares of 3M fell 9.6% on Friday after the profit warning.
