摘要： The liquid crystal display panel sequentially includes: a first polarizing plate; a first substrate; a first alignment film; a liquid crystal layer containing liquid crystal molecules; a second alignment film; a second substrate; and a second polarizing plate. The liquid crystal display panel is a normally black liquid crystal display panel capable of shifting into a transparent display state. The first alignment film and the second alignment film have been subjected to alignment treatment such that a first domain and a second domain in which alignment vectors are different from each other are arranged side by side in a column direction. In a plan view, a liquid crystal alignment axis of the first domain and a liquid crystal alignment axis of the second domain obliquely intersect a polarization axis of the first polarizing plate and a polarization axis of the second polarizing plate and are parallel to each other.

摘要： The light-emitting device includes a first lower electrode, a second lower electrode, a partition, a layer with high conductivity, light-emitting layers, and an upper electrode. The conductivity of the layer with high conductivity is higher than the conductivity of each of the light-emitting layers and lower than the conductivity of each of the lower electrodes and the upper electrode. The partition includes a first slope located on a first lower electrode side and a second slope located on a second lower electrode side. The thickness of the layer with high conductivity located over the first slope in a direction perpendicular to the first slope is different from the thickness of the layer with high conductivity located over the second slope in a direction perpendicular to the second slope.

摘要： Provided is a data processing apparatus including a correction circuit. In at least one embodiment, the data correction circuit acquires pixel data of a first pixel for display of a first color component and pixel data of a second pixel for display of a second color component, the second pixel being driven by a scanning signal line which drives the first pixel and being driven by a data signal line which is adjacent to the first pixel, and corrects the pixel data of the second pixel in accordance with a relationship between a value of the pixel data of the first pixel and a value of the pixel data of the second pixel. Thus, it is possible to cause a liquid crystal driving panel to perform uniform display without causing display unevenness even in a case where a halftone of a specific color component is uniformly displayed.
