Today’s LCD displays are thinner and more immersive than ever. LCD technology is continuously evolving to improve the touch response and quality of the display. Most displays are made of glass which is extremely thin in shape typically about 0.3-0.7 mm. In LCDs, a glass substrate is used to build the TFT (Thin-film transistors) layer that controls a color filter layer and liquid crystals.
For production efficiency, manufacturers are using large-sized substrates to cut into the appropriate size requirements of the product for instance LCD display panels are produced on top of a large substrate. The glass substrates that are the foundation of panels are called ‘Mother Glass’ and the generation is determined based on the size of the mother glass.
What is an LCD glass substrate?
LCD glass substrate is a specialized glass used in thin-film transistors (TFTs) LCDs to form the display of various products such as personal computers, laptops, mobile phones, game consoles, automotive navigation systems, and digital cameras/camcorders. LCD glass substrate layers consist of liquid crystals, a color filter, a polarizer, TFT, and a TFT substrate.
Why is LCD glass substrate high in demand for televisions?
The demand for high-resolution televisions is rapidly increasing as LCD technology is continuously growing. LCD glass substrates are widely used in televisions due to the usual size of televisions. Nowadays consumers are preferring bigger and wider televisions to enjoy vivid and fine pictures even in very large screen sizes.
TVs are usually bigger and wider compared to computers and laptops which results in increasing demand for LCD glass substrates for high-definition (HD) visuals and images.
New technological advancements in displays with higher resolution such as 4K and 8K TVs are being developed one after another which can create new pathways for the LCD glass substrates.
Global LCD Glass Substrate Market Size and Valuations
LCD Glass substrate enables high-resolution and rich color contrast for a better experience. The rapid growth in the television industry with large-sized screens and ultra-high definition (UHD) is likely to propel the demand for LCD glass substrates.
With this rapid growth in TV and laptop production, the global LCD glass substrates market size was valued at USD 7879.5 million in 2020 and is anticipated to reach USD 10090 million by 2028, expanding at a CAGR of 4.2% during the forecast period, 2021–2028.

For display, there are three major products and they are as follows:
- OA-10G (Alkali-free Glass Substrate): It has excellent surface smoother because it is made by overflow technology and is widely used as a substrate for liquid crystal display and OLED display.
- OA-11(Alkali-free Glass Substrate): OA-11 has particularly low deformation and deflection of gravity properties. This is both very thin and easy to handle and it is widely for OLED display and liquid crystal display, as well as a substrate for the formation of various thin films.
- OA-31(High Heat-resistant and Low Thermal Compaction Glass Substrate): This is widely used in tablets and smartphones. It is suitable for OLED and LTPS displays.
Conclusion:
LCD glass substrates are widely used in television, laptops, and automotive navigation system. Rising emerging economies and increasing technological & entertainment expenditures can produce new growth opportunities for the key players. Inventions such as the production of LCD screens using a single substrate and new upcoming substrate generations can drive market growth.
