Liquid crystal display device
A mobile phone is provided which includes a liquid crystal display device in which a front window and a touch panel are bonded together with an adhesive sheet, wherein a logo having plural layers is formed on a back side of the front window. A touch-panel flexible wiring substrate is mounted to the touch panel. A plane distance between an end portion of the plural layers of the logo and an end portion of the touch panel is set to greater than zero. With this configuration, it is possible to prevent a peeling stress on the adhesive sheet, even if a thickness of the adhesive sheet is smaller than the sum of a thickness of the touch-panel flexible wiring substrate and a thickness of the logo.
1. A display device comprising:
a front window including a logo;
a touch panel element which is bonded to the front window; and
a display panel,
wherein the touch panel element and the front window are bonded together with an adhesive material,
wherein the logo comprises a plurality of layers and is formed on a surface of the front window,
wherein a portion of the plurality of layers of the logo is provided on a first portion of the surface of the front window which is outside of a second portion of the surface of the front window which is covered by the adhesive material,
wherein the plurality of layers of the logo does not overlap the touch panel element in a plane view, and
wherein the plurality of layers of the logo includes two color resin.
2. The display device according to claim 1 , further including a flexible wiring,
wherein the flexible wiring is connected to a specific side of the touch panel,
wherein, when a thickness of the adhesive material is d 1 , a thickness of the portion of the plurality of layers of the logo is d 2 , and a thickness of the flexible wiring substrate is d 3 , the relationship d 1 <d 2 +d 3 is satisfied.
3. The display device according to claim 1 ,
where a distance, in a plane view, between an end portion of the plurality of layers of the logo and an end portion of the touch panel element is greater than 0.3 mm.
4. A display device comprising:
a front window including a logo;
a touch panel element bonded to the front window, and
a display panel;
wherein the touch panel element and the front window are bonded together with an adhesive material,
wherein a flexible wiring substrate is connected to a specific side of the touch panel element,
wherein the logo is formed on an inner surface of the front window, which inner surface faces the touch panel element,
wherein the logo is formed by two layers including a first layer and a second layer,
wherein a portion of the two layers of the logo is provided on a first portion of the inner surface of the front window which is outside of a second portion of the inner surface of the front window which is covered by the adhesive material,
wherein a distance, in a plane view, between an end portion of the second layer of the logo and an end portion of the touch panel element is greater than zero so that the second layer does not overlap the touch panel element in a plane view, and
wherein a color of the first layer is different from that of the second layer.
5. A display device comprising:
a front window including a logo;
a touch panel element bonded to the front window; and,
a display panel,
wherein a flexible wiring substrate is connected to a specific side of the touch panel element,
wherein the logo is formed on an inner surface of the front window, which inner surface faces the touch panel element,
wherein the logo is formed by three layers including a first layer, a second layer, and a third layer,
wherein an end portion of the second layer is covered by the third layer,
wherein a portion of the three layers of the logo is provided on a first portion of the inner surface of the front window which is outside of a second portion of the inner surface of the front window which is covered by the adhesive material,
wherein a distance, in a plane view, between an end portion of the second layer of the logo and an end portion of the touch panel element is greater than zero so that the second layer does not overlap the touch panel element in a plane view, and
wherein a color of the first layer is different from that of the second layer.
