Manufacturing method of mold and method for forming liquid crystal display using the same

A method for manufacturing a mold, comprising:

• forming a buffer layer on a substrate;
• forming a first photosensitive film on the buffer layer;
• etching the buffer layer and the substrate using the first photosensitive film as a mask to form a first groove;
• removing the first photosensitive film;
• forming a second photosensitive film covering the first groove on the substrate;
• and
• etching the substrate using the second photosensitive film as a mask to form a second groove having a different depth from the first groove.

A method for manufacturing a mold, comprising:

• forming a photosensitive film pattern on a substrate, the photosensitive film pattern comprising a first portion and a second portion having a greater thickness than the first portion;
• etching an exposed portion of the substrate using the photosensitive film pattern as a mask to form a preliminary first groove;
• removing the first portion to expose the substrate;
• and
• etching, using the second portion as a mask, the preliminary first groove and the substrate to form a first groove and a second groove.

A method for manufacturing a mold, comprising:

• forming a buffer layer on a substrate;
• forming a first photosensitive film on the buffer layer;
• exposing and developing the first photosensitive film to form a photosensitive film pattern comprising a first portion and a second portion having a greater thickness than the first portion;
• etching, using the photosensitive film pattern as a mask, an exposed portion of the substrate and the buffer layer to form a preliminary first groove;
• removing the first portion to expose the substrate;
• and
• etching, using the second portion as a mask, the preliminary first groove and the substrate to form a first groove and a second groove.

A method for manufacturing a liquid crystal display, comprising:

• forming a lower panel comprising a thin film transistor and a pixel electrode connected to the thin film transistor;
• forming a light blocking member and a spacer on the lower panel using a roll printing method, the roll printing method being implemented with a mold comprising a first groove having a first depth and a second groove having a second depth, the first depth being different than the second depth;
• forming an upper panel facing the lower panel, the upper panel being formed with a common electrode;
• and
• forming a liquid crystal layer between the upper panel and the lower panel.
