Abstract

The present invention provides a display module having: a display board on which a display element displaying an image is mounted; and a chassis on which the display board is mounted and which is placed on a circuit board. The chassis has a support board and a frame plate. The support board includes: a support section which supports a portion of the display board except for a corner section of the display board; and a depressed section which continuously expands from the support section and is formed such that a surface on a side supporting the display board is lower than the support section. The frame plate is placed on the circuit board while supporting the support board at a predetermined height with respect to the circuit board.

Claims

1. A display module comprising:

a display board on which a display element displaying an image is mounted; and

a chassis on which the display board is mounted and which is placed on a circuit board,

wherein the chassis has;

a support board having a support section which supports a portion except for a corner section of the display board and a depressed section which continuously expands from the support section and is formed such that a surface on a side supporting the display board is lower than the support section, and

a frame plate which is placed on the circuit board while supporting the support board at a predetermined height with respect to the circuit board.

2. The display module according to claim 1, wherein a conductor film is formed on a back surface of the support board facing the circuit board when the support board is placed on the circuit board.

3. The display module according to claim 1, wherein the depressed section is formed so as to protrude on a side of the back surface of the support board.

4. The display module according to claim 1, wherein a boundary portion between the support section and the depressed section on a surface of the support board has a chamfered shape.

5. The display module according to claim 1, wherein the support board has a rib which protrudes from a back surface of the support section, and abuts a component mounted on the circuit board to prevent excessive deformation of the support section when the support section is pressed.

6. A portable terminal apparatus having a radio communication function comprising:

a display module having a display board on which a display element displaying an image is mounted; and

a chassis on which the display board is mounted and which is placed on a circuit board,

wherein the chassis has;

a support board having a support section which supports a portion except for a corner section of the display board and a depressed section which continuously expands from the support section and is formed such that a surface on a side supporting the display board is lower than the support section, and

a frame plate which is placed on the circuit board while supporting the support board at a predetermined height with respect to the circuit board.

7. The portable terminal apparatus according to claim 6, wherein a conductive film is formed on a back surface of the support board facing the circuit board when the support board is placed on the circuit board.
