A liquid crystal display panel is provided with a light-shielding film, and a plurality of subpixels arranged in a matrix. The subpixels each include a first electrode formed on a first substrate, a second electrode formed to be located upper than the first electrode, and a color filter formed on a second substrate. The second electrode has a plurality of linear portions. The subpixels are disposed adjacently along the direction of display lines, and any two of the adjacent subpixels have the same color of color filter. The light-shielding film is formed on the second substrate not to cover the pixel boundary between the two adjacent subpixels but to cover pixel boundaries of the remaining subpixels. The second electrodes of the two adjacent subpixels are formed separately, and assuming that the two adjacent subpixels are first and second subpixels, at least the second electrode of the first subpixel is disposed also to an area of the second subpixel beyond the pixel boundary between the first and second subpixels. Such a configuration favorably increases an aperture ratio of a liquid crystal display device including a color filter.

According to an aspect of the present invention, the first filters, which correspond to the two or more first colors that contribute to obtaining a brightness signal more than the second colors, are disposed within each pixel line in first direction to the fourth direction of the color filter arrangement, and it is configured so that the ratio of the number of pixels of the first colors corresponding to the first filters is larger than the ratio of the number of pixels of each color of the second colors corresponding to the second filters of two or more colors other than the first colors. Accordingly, the degree of reproducibility of the synchronization processing in a high-frequency wave area can be increased and the aliasing can be suppressed.

A DFB quantum cascade laser element that can reliably CW-oscillate a single-mode light even at room temperature or a temperature in proximity thereof is provided. In a quantum cascade laser element 1, a top-grating approach for which a diffraction grating 7 is formed on a laminate 3 is adopted, and thus in comparison with a buried-grating approach, deterioration in temperature characteristics of the laser element and decline in the yield and reproducibility are suppressed. In addition, since the thickness of a cladding layer 5 located between an active layer 4 and the diffraction grating 7 is within a range of 42±10% of the oscillation wavelength, weakening of light seeping from the active layer 4 to the diffraction grating 7 or an increase in light leakage is prevented. Consequently, by the quantum cascade laser element 1, a single-mode light can be reliably CW-oscillated even at room temperature or a temperature in proximity thereof.

A charged particle beam device enabling prevention of degradation of reproducibility of measurement caused by an increase of the beam diameter attributed to an image shift and having a function of dealing with device-to-device variation. The charged particle beam device is used for measuring the dimensions of a pattern on a specimen using a line profile obtained by detecting secondary charged particles emitted from the specimen when the specimen is scanned with a primary charged particle beam converged on the specimen. A lookup table in which the position of image shift and the variation of the beam diameter are associated is prepared in advance by actual measurement or calculation and registered. When the dimensions are measured, image processing is carried out so as to correct the line profile for the variation of the beam diameter while the lookup table is referenced, and thereby the situation where the beam diameter is effectively equal is produced irrespective of the position of the image shift. Whit this, measurement by the charged particle beam excellent reproducibility can be carried out.
