Liquid crystal display panel, color film substrate, and thin film transistor substrate

A color film substrate, the color film substrate comprising:

• a first substrate;
• a black matrix disposed on the first substrate;
• a pixel layer disposed on the black matrix;
• and
• a protective layer disposed on the pixel layer;
• wherein the protective layer is provided with a photo spacer or/and a recess;
• the photo spacer on the color filter substrate is used for nesting with a recess on a thin film transistor substrate to be integrated with the color filter substrate, and the recess on the color filter substrate is used for nesting with a photo spacer on the thin film transistor substrate to be integrated with the color filter substrate.

A thin film transistor substrate, the thin film transistor substrate comprising:

• a second substrate;
• a semiconductor layer disposed on the second substrate;
• a gate insulating layer disposed on the semiconductor layer;
• an interlayer insulating layer disposed on the gate insulating layer;
• a second metal layer disposed on the interlayer insulating layer;
• a flat layer disposed on the interlayer insulating layer and covering the second metal layer;
• and
• a pixel electrode disposed on the flat layer;
• wherein the flat layer is provided with at least two spaced-apart vias, a photo spacer or/and a recess is disposed on the flat layer between two adjacent vias, the photo spacer on the color filter substrate is used for nesting with a recess on a thin film transistor substrate to be integrated with the color filter substrate, and the recess on the color filter substrate is used for nesting with a photo spacer on the thin film transistor substrate to be integrated with the color filter substrate.
