Abstract

A portable device and method of manufacturing a display device includes a display panel having a glass substrate and a polarizer adhered to the glass substrate, a touch panel which is made of resin material and adhered to the polarizer of the display panel by a first adhesive material, and a front window which is made of glass and adhered to the touch panel by a second adhesive material. One of the first adhesive material and the second adhesive material is an adhesive sheet, and an other of the first adhesive material and the second adhesive material is an ultraviolet-curing adhesive material.

Claims (18)

1. A display device comprising:

a display panel having a first substrate, a polarizer, and a semiconductor chip,

a touch detecting substrate on the display panel, and

a first adhesive material disposed between the display panel and the touch detecting substrate,

wherein the semiconductor chip mounts on an edge region of the first substrate,

the touch detecting substrate has a first portion which does not overlap with the polarizer of the display panel,

the first portion of the touch detection substrate overlaps with the semiconductor chip, and

a height of a top surface of the semiconductor chip from the first substrate is smaller than a height of a top surface of the polarizer from the first substrate.

2. The display device according to claim 1 ;

wherein a front cover is disposed on the touch detecting substrate,

the area of the front cover is larger than the area of the touch detecting substrate.

3. The display device according to claim 2 ;

wherein a second adhesive material is disposed between the touch detecting substrate and the front cover.

4. The display device according to claim 3 ;

wherein the display panel has a second substrate facing the first substrate,

the display panel includes a liquid crystal between the first substrate and the second substrate.

5. The display device according to claim 3 ;

wherein the semiconductor chip is thicker than a sum of the polarizer and the second substrate.
