Abstract

The LCD module according to the present disclosure includes a liquid crystal cell and a mold frame accommodating the liquid crystal cell. The mold frame includes a support supporting the liquid crystal cell in a thickness direction of the liquid crystal cell and a guide for limiting movement of the liquid crystal cell in a planar direction of the liquid crystal cell. The guide includes a corner-part guide disposed to face a corner part on the corner part of at least one side of the liquid crystal cell, and an inner-part guide facing an inner part being a part of the side other than the corner part, and being adjacent to the corner-part guide with distance. A gap between the liquid crystal cell and the corner-part guide is larger than a gap between the liquid crystal cell and the inner-part guide.

Claims (25)

1. An LCD module comprising:

a liquid crystal cell; and

a mold frame accommodating the liquid crystal cell and including:

a support supporting the liquid crystal cell in a thickness direction of the liquid crystal cell; and

a guide for limiting movement of the liquid crystal cell in a planar direction of the liquid crystal cell, the guide including:

a corner-part guide disposed to face a corner part on the corner part of at least one side of the liquid crystal cell; and

an inner-part guide facing an inner part being a part of the side other than the corner part, and being adjacent to the corner-part guide with a gap therebetween so that the inner-part guide and corner-part guide are separated by a distance,

wherein a gap between the liquid crystal cell and the corner-part guide is larger than a gap between the liquid crystal cell and the inner-part guide,

wherein the inner-part guide is divided into a plurality of inner part guides,

wherein a gap between the liquid crystal cell and the inner-part guide adjacent to the corner-part guide is smallest of all gaps between the liquid crystal cell and the plurality of inner part guides, and

wherein the gap between the liquid crystal cell and the corner-part guide is larger than any gap between the liquid crystal cell and the plurality of inner part guides.

2. The LCD module of claim 1 , wherein a distance from an apex of the liquid crystal cell to the inner-part guide is 3 to 9% of a length of the at least one side of the liquid crystal cell that faces the inner-part guide.

3. The LCD module of claim 1 , wherein the gaps between the liquid crystal cell and the plurality of inner part guides are not equal in length.

4. The LCD module of claim 1 , wherein the at least one side of the liquid crystal cell is a long side of the liquid crystal cell.

5. The LCD module of claim 1 , wherein the at least one side of the liquid crystal cell is a short side of the liquid crystal cell.

6. An LCD module comprising:

a liquid crystal cell; and

a mold frame accommodating the liquid crystal cell and including:

a support supporting the liquid crystal cell in a thickness direction of the liquid crystal cell; and

a guide for limiting movement of the liquid crystal cell in a planar direction of the liquid crystal cell, the guide including:

a corner-part guide disposed to face a corner part on the corner part of at least one side of the liquid crystal cell; and

an inner-part guide facing an inner part being a part of the side other than the corner part, and being adjacent to the corner-part guide with distance,

wherein a gap between the liquid crystal cell and the corner-part guide is larger than a gap between the liquid crystal cell and the inner-part guide,

the inner-part guide is divided into a plurality of inner part guides in the one side of the liquid crystal cell, and

a gap between the liquid crystal cell and the inner-part guide adjacent to the corner-part guide is smallest of all gaps between the liquid crystal cell and the plurality of inner part guides.
