It is the largest increase in six years boosted by stronger demand for handset displays.

In a filing to the Korea Exchange, the LG affiliate said sales were down 2.1 percent.

Despite the drop in sales, its net profit jumped 119 percent on stronger margins.

This means that the company can pay its first dividend in four years.

Analysts were positive about the result and its outlook for the first quarter of this year.

LG supplies displays to Apple, HP, Dell, Sony and other top-tier Chinese TV makers.

The analyst said LG Display will benefit most among its chief Japanese and Taiwanese rivals as the Korean company is better in terms of output commitment, on-time delivery and better pricing.

LG Display, which is 37.9 percent owned by LG Electronics, said its moves to boost the sale of UHD displays for TVs to leading Chinese TV manufacturers also paid off.
