Abstract
A method for fabricating a color filter substrate including the following procedures is provided. First, a substrate is provided and a color filter layer is formed thereon. Next, a plurality of sensing spacers is formed on a part of the color filter layer. Then, a planarization layer is formed to cover the color filter layer and expose the sensing spacers. Next, an electrode layer is formed to cover the planarization layer and the sensing spacers. After that, a plurality of main spacers is formed on a part of the electrode layer excluding disposing regions of the sensing spacers, wherein a step height is formed between the main spacers and the electrode layer above sensing spacers.
