To enable acquisition of image data in multiple tone levels in a short capturing time, a liquid crystal display deviceincludes a photodiode having sensitivity R, a capacitor having capacitance C and configured to store a charge in response to an electric signal converted by the photodiode in a state where an initial voltage V is applied thereto, a SRAM configured to retain binary data which indicate as to whether or not an amount of charge stored in the capacitor is equal to or above a threshold voltage Vth, an image capturing control unitconfigured to generate pixel data in multiple tone levels based on the binary data outputted from the SRAM of a plurality of adjacent pixels. Here, at least any one value of R, V, C, and Vth in each of the pixels is set to a different value from relevant values of other adjacent pixels.

Liquid crystal display device provided with an image capturing function

A communication terminal device includes a first display part configured to display streaming sub information, a second display part configured to display streaming main information related to the streaming sub information, a sub information reception unit configured to receive the streaming sub information sequentially transmitted from an information providing device and to display the received streaming sub information on the first display part, a request transmission unit configured to transmit to the information providing device an information request signal for requesting the streaming main information related to the streaming sub information displayed on the first display part, and a main information reception unit configured to receive the streaming main information and to display the streaming main information on the second display part.
