Display Glass Revenues Up 11% in Q3 2025 on Strong Volume, Price Increases
Price increases in the second half of 2024, combined with strong utilization by panel makers in Q3 2025, drove display glass revenues to their highest value in at least 10 years, according to Counterpoint Research’s Quarterly Display Glass Report, released last week. Display glass revenues increased 1% QoQ and 11% YoY in the third quarter, and although we expect that revenues will decline in the fourth quarter, they will increase 11% YoY for the full year of 2025.
The Display Glass Report tracks capacities and shipments for all major glass makers across all LCD and OLED display fabs. The report combines Counterpoint’s comprehensive insights 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 South 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 also includes a supply matrix covering 26 panel makers.
Industry capacity for display glass increased by less than 1% QoQ but decreased by 2% YoY in Q3 2025. Corning shut down capacity in Japan in H2 2024 after Sharp’s Gen 10 fab shutdown. On the other hand, domestic Chinese glass makers have added Gen 8.5 capacity during 2023-2025. Capacity remains somewhat higher than demand.
Glass maker shipments of display glass in Q3 2025 increased 1% QoQ and 4% YoY. Shipments are expected to decline 3% QoQ in Q4 2025 to and decrease by 1% QoQ in Q1 2026.
The Gen 8 and above share of the display glass market reached an all-time high of 80% in Q2 2024 but has declined slightly in 2025 after the shutdown of Sharp’s Sakai Gen 10 fab. The share of the remaining Gen 10.5 fabs in the glass market fell to 23% in Q2 2025 as several of the fabs slowed down in June and July, but they are projected to recover to 24% in Q4 2025. Meanwhile, Gen 8.x continues to represent more than half of the market.
A view of the market in terms of regions demonstrates the dominance of Chinese panel makers in the display industry and the shrinking relevance of South Korea and Japan. As both Samsung Display and LG Display have shifted to OLED and closed LCD lines, their total display capacity in South Korea has decreased. Their glass demand has further reduced because all the OLED capacity added since 2017 requires only one piece of glass, whereas LCD requires two. Ten years ago, South Korea was the biggest region in terms of glass demand, and its share was 27% at the beginning of 2018, but we forecast that it will fall to less than 6% in Q4 2025.
The report also gives a split of the glass market by backplane type, showing the importance of more advanced backplanes in the display industry. Despite the growth of OLED, industry workhorse amorphous silicon (a-Si) glass substrates continue to make up close to 90% of display glass demand. This share is declining but slowly because of high fab utilization for LCD compared to OLED. We expect that the a-Si share will hold steady at about 88% in 2025.
The report provides tables of glass prices by Gen size for a-Si and LTPS glass. Glass is priced in Japanese yen across the industry, and while glass prices in the display industry vary by volume and by customer, the report provides average prices. Corning announced price increases in both 2023 and 2024. By Q1 2025, Corning declared that it had succeeded in implementing a double-digit price increase in both years (in yen terms). We estimate that glass prices were flat QoQ in Q3 2025 but up 7% YoY and remain at their highest point since Q4 2016.
Corning remains the leading glass maker both in terms of volumes and revenues and its share held steady QoQ in Q3 2025. With volume increasing 1% QoQ and price flat QoQ in Q3 2025, revenues increased 1% QoQ and 11% YoY. We forecast that revenues (in yen) will be down 3% QoQ in Q4 2025 and down another 1% QoQ in Q1 2026.
Counterpoint Research’s Quarterly Display Glass Report tracks glass capacity and shipments for all major glass makers across all LCD and OLED display fabs, providing pivot tables that allow splits by region, panel maker, backplane type and TFT Gen Size. The report includes prices for a-Si and LTPS glasses for Gen sizes 1 to 10.5, quarterly history from Q1 2019, and a forecast through Q1 2026.
