The display industry has been increasingly dominated by China, and the best example of that dominance is the display glass market. China’s share of display glass demand reached an all-time high and exceeded 70% in 2023, according to the latest update to DSCC’s Display Glass Report, released last week.

The Display Glass Report tracks glass capacity and shipments for all major glass makers across all LCD and OLED display fabs. The report combines DSCC’s comprehensive insight into industry capacity and utilization with an in-depth understanding of display glass and the supply chain. The report outlines capacity by region in each of the four regions of display glass production: Japan, China, Taiwan and Korea, and covers glass shipments in Gen sizes from 1 to 10.5. The report details glass shipments for the three major suppliers to the display industry, Corning, AGC and NEG, along with other glass suppliers. The report includes a supply matrix covering 26 panel makers.

After a 10% Y/Y decline in 2022, display glass shipments stabilized in 2023 and recorded a 2% increase Y/Y in volume terms. Glass shipments declined 10% in Q4’23 as LCD demand softened and are expected to decline another 5% Q/Q in Q1’24 before slowly recovering through the rest of the year.

A view of the market by region demonstrates the increasing dominance of the display industry by China panel makers and the shrinking relevance of Korea in the display glass market. Ten years ago, Korea was the largest region for glass demand, and Korea’s share was 27% at the beginning of 2018 but hit a low point of only 5% of the glass market in Q1’23. China’s portion of worldwide display glass demand, which was only 40% in Q1’18, increased to an estimated 71% in 2023 with growth in new capacity and shutdowns of Korea capacity.
