The completely-transmitting sections and the light-blocking sections are arranged alternate with each other. The light-blocking sections each include a non-light-transmitting sub-section and N light-transmitting sub-sections arranged between the non-light-transmitting sub-section and an adjacent one of the completely-transmitting sections. The N light-transmitting sub-sections have light transmission rates that are increased, step by step, in a direction from the non-light-transmitting sub-section to the completely-transmitting section, where N≥22 and N is an inter. Through modification of the structure of mask, grooves formed in a planarization layer of a non-display section with such a modified mask would have sidewalk that are smooth and the sidewalls having gentle slopes so that no residue of photoresist remains in a subsequent process."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Mask having intermediate light-transmitting sub-sections of stepwisely increased transmission rates","description":"A mask includes a plurality of completely-transmitting sections and a plurality of light-blocking sections.
