We successfully demonstrate a 1.89‐inch SLMoG (spatial light modulator on glass) driven by oxide BCE (back channel etch) TFTs (thin‐film transistor). It is necessary for SLM to have very fine pixel pitch and large panel size for realizing high display quality of digital holography. To confirm such technical demands, we fabricate 1.89‐inch SLMoG with 20‐μm pixel pitch, and apply ECB (electrically controlled birefringence) LC (liquid crystal) mode for light phase modulation. In this article, we report the results of demonstration and discuss technical issues of SLMoG technology.
