摘要： The present invention makes it possible to recognize proximity of a coil without an increase in material cost and production cost. A liquid crystal display panel includes a TFT substrate (6) and a CF substrate (7). A touch panel (2) includes (i) a plurality of touch sensing electrodes (3) which are provided on the TFT substrate (6) so as to detect an electric capacitance between the touch panel (2) and a subject of a touch or a change in the electric capacitance and (ii) a proximity sensing electrode (4) which is provided on the CF substrate (7) so as to detect proximity of a coil (10).

摘要： Provided is a touch-panel-equipped display device that is capable of detecting a touch on a side surface of a case (1) at a high accuracy by a simple controlling operation, without any hardware such as expensive sensors being provided additionally. In the touch-panel-equipped display device, a side surface electrode part can be electrically connected by capacitive coupling with a Y-direction electrode part. A change in capacitive coupling when the side surface electrode part is touched by a finger or the like, therefore, is reflected in a sense signal acquired by the Y-direction electrode part. In other words, in the touch-panel-equipped display device, a touch on the side surface electrode part can be detected using the sense signal. The touch-panel-equipped display device, therefore, is capable of detecting a touch on the side surface electrode part by using hardware and signal processing for touch detection in a conventional touch panel.

摘要： A display device (1) is provided that includes a display panel having a display region P; a transparent cover (16) having a top surface parallel to a surface for displaying the image, and a side surface connected to the top surface; a touch panel; and a case (17) for housing the display panel and the touch panel. The touch panel is capable of sensing contact or approach of an object at at least a part of an outer peripheral line of the top surface of the transparent cover (16). At the part of the outer peripheral line of the transparent cover (16), at which contact or approach of an object can be sensed by the touch panel, a part of the outer peripheral line that is recessed inward or is protruded outward is formed as a deformed part (16a).

摘要： There are provided an antenna device with improved antenna performance while suppressing a decrease in yield and a decrease in viewability, and a display device including the same. The antenna device includes an antenna substrate, a first antenna pattern formed on a first main surface of the antenna substrate, and a second antenna pattern formed on a second main surface opposite to the first main surface of the antenna substrate. The first antenna pattern and the second antenna pattern are formed such that positions on the front and back of the antenna substrate coincide with each other, and at least a part of the antenna substrate is transparent to transmit an image.
